      I have two WANs. I create separated VPN servers for each, using the wizard, both on IPv4 UDP port 1194, assigned separately to each interface. I have dynamic DNS already working for both WANs, and I then exported the 2 client profiles to my phone.

      I was surprised to see that the phone could only connect to the first VPN server, but not the second. On the second one, it sat for a while "waiting for server" and then timed out.

      I couldn't figure out what was wrong. There was nothing obvious in the logs, including firwall logs.

      Then, I re-ran the wizard and changed the second VPN to TCP and exported the new profile. This time, it worked !

      Lastly, I ran the wizard one more time, this time with UDP port 1195. It also worked !

      I think there is a port conflict going on. It should be possible to have two VPN servers using the same port, as long as they are bound to distinct interferences, and not to "any" address.
      Am I missing something, or is there a way to make that happen ? It's also possible there is a problem with the rules generated by the Wizard.
