I have installed OpenConnect via Entware-NG and it runs normally, creating a tun0 interface. I can ping, traceroute and ssh to devices on the VPN network from the router's console.

I cannot do this from other machines on the LAN. No traffic is routed over the VPN from any LAN devices.

I have to bounce off the router via...
Code:
ssh -t root@router "ssh user@remote-host"
...which is less than ideal.

Do I need to do something console or UI side to route traffic destined for that domain over the tun0 interface, to that network?

Do I need to craft iptables rules? Can you do this for an entire domain?

What is the VPN tunnel connected to?

Is it site-site or a site-Internet(commercial provider)?

The network behind the server needs a route to the network used on your LAN:
