Used this AMI ami-b7418dd7 followed this guide: https://docs.openvpn.net/how-to-tutorialsguides/virtual-platforms/amazon-ec2-appliance-ami-quick-start-guide/ Now, when a user coects to the VPN I want all of their normal inteet traffic to go through the public inteet, but when they are trying to access one of our inteal systems I want that traffic to go through the VPN. How? I've seen a lot of other answers, and I've found very few of them helpful. On this official AMI from openvpn, I can't find any server.conf or client.conf files that so many answers seem to point toward. Any help appreciated, this is the single stupidest task to be given as a software engineer, not an IT / systems-administ...

I want to create an Outlook mail rule for every company that I deal with so that @xyzcompany.com goes to xyz company folder and @abccompany.com goes to abcompany etc.. without creating a rule for each one. It would have to create folders for new companies that I haven't dealt with. If anyone has any ideas I would be most grateful. Let's block ads! بخوانید...

I have a Synology NAS (DSM 5.4) on which I run an OpenVPN server (on port tcp/1194, IP is 192.168.1.10). I have forwarded the port 64666 on my exteal IP to that address and port on my access router (a TP-Link AS1200). The problem: I caot coect with an OpenVPN client from an inteet host: Tue Aug 23 15:05:37 2016 Attempting to establish TCP coection with [AF_INET]myip:64666 [nonblock] Tue Aug 23 15:05:47 2016 TCP: coect to [AF_INET]myip:64666 failed, will try again in 5 seconds: Coection timed out (...) When ruing an nmap from within the inteal network (the one the NAS is on) I get a correct reply: C:WindowsSystem32>nmap 192.168.1.10 -p 1194 -sV Starting Nmap 7.12 ( https://nmap.org ) ...

I spend two days trying to compile my code with header as cross compiler for OpenWrt I am using LinksysWRT54GL, and mipsel architecture.

Please redirect me if I'm posting this question in the wrong place. Background: I'm currently ruing DD-WRT v3.0-r29519 std (04/25/16) on my TP-Link Archer AC1750. For QoS, I have HTP scheduling set up with a very simple set of rules defined in the DD-WRT GUI at */QoS.asp. I've searched through dozens of DD-WRT forum entries to try and understand this code, per the DD-WRT wiki page 1 17 * * * root /usr/sbin/svqos `nvram get wshaper_downlink` `nvram get wshaper_uplink` `get_wanface` `nvram get wan_mtu` 0 */6 1-17 * * * root /usr/sbin/svqos stop 0 `get_wanface` 0 0 I would like to enable my GUI-set QoS settings from 12 PM to 5 AM, and my guess is that the code would look like this 1 00 * * ...

This is where DHCP Servers come in. It will send a discovery request on the network using the ip 255.255.255.255 and the source ip being 0.0.0.0 since it doesn't know its own ip yet. However this is where MAC Addresses come into play as well as the Discover packet is encapsulated into a Data Link Layer Etheet frame to the target MAC Address of FF:FF:FF:FF:FF:FF and the source being whatever the network interface MAC address is. The first Switch that recieves the packet for FF:FF:FF:FF:FF:FF will forward that discover packet on out of every single switch port except the one it came from since it doesn't know who FF:FF:FF:FF:FF:FF is either until the DHCP server sees it. If the DHCP servers is...

new to this so bear with me how to route/setup multiple ips on a VM for some reason i receiving every packet on on the interface with the lowest metric (and sometime on a random one) i can ping all ips the sites are also working sort of pinging ip 1.2.3.4 and i receive the packet on MAC 00:11:22 pinging ip 10.20.30.40 and i receive the packet on MAC 00:11:22 pinging ip 100.0.0.4 and i receive the packet on MAC 00:11:22 ifconfig shows the proper MAC addresses for the interfaces Let's block ads! بخوانید...

I caot alter my modem firmware and there's no legal way to enable bridge mode. I want to add a router so that I can have complete control over the network. If I use DMZ to achieve this, how secure am I? What would happen if an attacker is able to breach my less-secure modem (that is also a router) and change some settings like DNS? Is there any approaches to minimize risks? Router/Modem from my ISP¹ => DMZ => Router with DHCP and NAT => All my devices ¹wifi disabled, no wired devices coected, but I can't disable NAT or DHCP Let's block ads! بخوانید...

The easiest way to do this with a DNS service. If you subscribe to Alteate DNS or Open DNS, they may be able to get most of that done for you with very little configuration. Just have your router hand out their DNS server IPs, and you may be good to go. I believe there are free service tiers at both. Alteatively, while probably not possible on your router (due to hardware lacking the required horsepower), Pi-Hole is a project that does exactly what you're looking for as an actual service ruing on your network. Others have done it differently. It can probably be adapted with very little work for a more powerful router ruing an open OS like Tomato, DD-WRT, OpenWRT, HyperWRT, Gargoyle, or ViOS ...

up vote -2 down vote favorite I have a ASUS router RT-AC66U which has a firewall section but I am a bit confused which ports I need to block for P2P and FTP and eventually other services which will drain the coection. The firewall does have "Filtered ICMP packet types" in case that is a simpler way to setup my firewall. Let's block ads! بخوانید...

I have a inteet coection on my laptop which is provided by a router(let's call it router 1), so my laptop is coected to the LAN of router 1. There is a wireless router which is also coected to the same LAN and uses the inteet coection provided by it, let's call this router router 2. All the devices coected to router 1 have to use their own static ip to coect to the inteet. And the speed of the inteet coections are limited. The inteet speed that router 2 gets through this inteet coection is much higher than my laptop's coection's speed limit. So I am trying to coect to router 2 to access the inteet. I know the password for the inteet coection that router 2 provides. I also have administrative...

I thought I knew a thing or two about VPNs until now. For years, I've had a nice site-to-site VPN with two Cisco SRP527w routers. Now, I have a new router in my home office (Asus RT-AC88U) and I'm confused about my VPN. The Cisco at the office is configured under the heading of "Site to Site IPSec VPN") with use of an IKE Policy and a IPSec Policy. The Asus at home offers VPN Client Profiles of PPTP, L2TP or OpenVPN. Based on that information, am I right in saying these protocols are not compatible? And if so, are there any suggestions for other options? Let's block ads! بخوانید...

I have 3 computers ruing windows 7 coected to a wireless router and each computers are assigned with dynamic ip in the range 192.168.0.30 - 192.168.0.253, subnet mask 255.255.255.0, gateway (router) 192.168.1.254. I have problem coecting from one pc to another, ie. when I try to ping the other computer, I sometimes get reply, and sometimes i get 'destination host unreachable". I have tued off windows firewall. What could be the cause and how do I troubleshoot to find the problem? Let's block ads! بخوانید...

Ive got a mobile router ruing of a mobile SIM which I would like to access exteally through DDNS. The public IP is 49.x.x.x however within the router (Comset CM685 Mobile Router) it says that the WAN IP is 100.x.x.x. I believe this may be because of the the Carrier-Grade NAT. Firstly, should the WAN IP ideally be the same as the Public IP? Secondly, Is there any way i can access this router remotely? If i try to ping any of the IPs it simply times out. DDNS points to the public IP but it seems to lead nowhere. Any advice would be highly recommended. Thank you all. Let's block ads! بخوانید...

If I try to fetch this resource (CSS file) with my browser(s): https://secure.skypeassets.com/apollo/2.0.823/css/components.css I get this error: With Firefox: This Coection is Untrusted You have asked Firefox to coect securely to secure.skypeassets.com, but we can't confirm that your coection is secure. Normally, when you try to coect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do? If you usually coect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue. However, if I coect my etheet cable dir...

There is a Technicolor TC7200.U left from my last flat and inteet provider. This one is still configured like the inteet provider prepared it in the first place, which means that I can't use it in my new flat. How can I make the modem/router usable (for anything) again? Has anyone of you an idea or for instance knows a tutorial to replace the firmware on it? I wasn't able to find a lot of information about the TC7200.U in the last hours and nothing usable to make the modem/router reusable. Does one of you has an idea? Thanks for thinking about the question ;). Let's block ads! بخوانید...

So, this weekend I attempted to install DD-WRT on my router (WNR3500Lv2, latest Kong build)... and I'm not sure how it went: I can no longer reach my router admin page. 30-30-30 resets don't appear to have any effect. router boots, and lights up properly (although might be taking a while). wireless light is on, but nothing I have can see the wireless network. Wired coections work, sort of: I can potentially ping other machines on the network(might only work if the destination requested a static ip); tuing on network discovery does result in the computers being visible in Windows. Haven't checked inteet coectivity yet, plaing on this afteoon. No default gateway is assigned, and the auto-assig...

I want all traffic coming from 192.168.2.10 on interface eth0 to be masqueraded and forwarded out through interface tun0. I want the response to come back through tun0. I don't want other traffic on interface eth0 to be affected. This is what I have: # iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE # iptables -A FORWARD -i tun0 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT # iptables -A FORWARD -i eth0 -s 192.168.2.10/32 -o tun0 -j ACCEPT # ip rule add from 192.168.2.10/32 table 100 # ip route add default via 10.8.0.1 table 100 Is this configuration correct?

My router and wifi work fine for all devices. However I prefer to use an etheet when I want to play online games with my laptop. When I start the computer with an etheet b/t my laptop and the router, the inteet and wifi drops entirely for all devices and even the laptop w/ the etheet doesn't have inteet. If I restart the router and modem while the laptop is etheet'ed to the router, it says there's an inteet coection, but nothing loads. So then I restart the laptop and the inteet coection drops again. What could cause this? Let's block ads! بخوانید...
