Autostarting sshuttle as root

As the title says, I'm experiencing problems when autostarting sshuttle when I log in.
I'd prefer to let this program as root.
On the client I'm ruing Arch Linux with LXDE, and LXDM to login.
This client needs to coect to a Debian server over port 443.
Worth to mention: the command in question (sudo sshuttle -r 'user@server':443 0/0 works fine when executing manually in a terminal window.
Tried using the xinitrc for it, maybe it's possible to link a bash script to the xinitrc and execute this command from there? Again, it needs to have root without having to enter password (in autostart commands I want it completely executed without having it ask me for any input).
I'm thinking of adding it to anacrontab, but I'm hesitant since I don't completely understand this tool.

I assume I gave as much information as I can, but if anything misses, please let me know, I'll include it to this post then.

Thanks in advance for your guidance!
