Can't access web interface from VPN network

[dasher]

Hi there,
I have Proxmox and several LXC containers running on 10.0.0.0/24 network. I'm able to access the web interface from another machine on the same network. I also have a dedicated VPN router. When I VPN into it I'm put on 10.2.0.0/24 network and able to access any running container. However I can neither ping the Proxmox server by IP nor access its web interface. It seems like Proxmox is only allowing local connections, even though the VPN firewall allows all traffic in.
Do I need to do additional configuration on the Proxmox side to allow the access?

Thanks.

To interconnect two networks you (usually) need to use a router, right?

My personal pitfall (some time in the distant past) was to realize that not only to reach the destination had to be implemented - my attempts just "did not work".

But also the destination had to know how to successfully send back data to the original source.

Routing required both communication partners to know a way to reach the other one

Note that I am not saying that this is your problem - I just wanted to mention a well-known pitfall...
