Actually, you can configure Webmin to listen on multiple IP addresses at Webmin -> Webmin Configuration -> Ports and Addresses.

I think that is very useful. By the way, I do not understand why a bind to 127.0.0.1 makes it possible to contact on a vpn-port.

That said, we could support multiple bind addresses if this would be a useful feature?

Wait did you edit that bind line manually? Because it only supports a single IP address currently..

Strange: on an other server in webmin.conf bind=127.0.0.1, restricted access via proxy webserver ánd access via vpn 10.203.111.2 is possible.

On an other server bind=10.203.133.2 works. The only access is via VPN.

10.203.122.1 dev tun122 proto kernel scope link src 10.203.122.2
IP 10.203.112.2 is local on tun122.

On other systems this runs good.

When I remove 10.203.122.2 from bind= webmin runs. But then I can only log in via the restricted proxy webserver. It is important to have the possibilty to log in via the vpn.

Seems like that IP is on a different system? Try just removing that bind= line from miniserv.conf and then starting Webmin.

Is the IP address 10.203.122.2 still active on your system? From the error, it looks like it might not be ..
