Forums Bug Reports /socklisten, upnp and dual socket

When a /socklisten socket is bound to ipv6, mIRC is not attempting to forward the port using upnp if the -p switch is used, which is correct because ipv6 does not have port forwarding.

However dual socket changed the game, now there is a problem: when you create a listening dual socket, you bind to ipv6, but you're allowing ipv4 as well, therefore mIRC should actually be forwarding the port with upnp on ipv4 in this case.

Upnp works on ipv4 -- correct

Upnp doesn't work on ipv6 -- correct

Upnp doesn't work on dual socket for ipv4

Thanks this issue has been fixed for the next version.
