Proxmox OpenVPN client can't coect to containers with 2 networks

I have a Proxmox server ruing several containers, some with exteal and inteal networks, some with only inteal. The Proxmox server itself has OpenVPN server installed on it, and I can coect to it and ping/traceroute the server itself, as well as containers with only an inteal network. However, trying to reach any container that has an exteal network doesn't work. Traceroute from the VPN client shows one hop to the VPN server, then times out.

The containers with only the inteal network can successfully coect to the containers with two networks, and vice versa. The Proxmox host can coect to both types, and vice versa. The only place I'm having trouble is from the VPN client to containers with 2 networks.

Here are some configurations to explain what I'm doing (abbreviated):

Proxmox ifconfig (vmbr0 is bridged to eth0)

vmbr0     Link encap:Etheet  HWaddr x:x:x:x:x:x  
          inet addr:149.x.x.x  Bcast:149.x.x.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

Proxmox route (VPN routes also shown, VPN network is 10.5.0.0/24):

I have tried making a route on Proxmox host to direct all requests for 10.55.55.0/24 to vmbr0 but it didn't change anything. I'm a web developer by trade, so I'm not super familiar with networking. Any help would be appreciated!
