Product Version3.2.10.1 
Fixed in Version3.2.10.2 
Summary0004194: IRCd will not connect to IPv4 server
Description3.2.10.1 will not connect an IPv4 link while IPv6 listen block is specified.
Steps To Reproducehave both ipv4 and ipv6 listen blocks.
try to connect to an ipv4 server (connection will fail, no route to host)

Workaround:
comment out ipv6 listen block(s)
restart unreal
connection succeeds
uncomment ipv6 listen blocks
rehash

I wrote this as a blocker because it really should be fixed for 3.2.11.
Additional InformationWith ipv6 listen blocks:

Which OS?

And does it have to do with the order of listen blocks? In other words: if the IPv4 listen block is before the IPv6 listen block (or vice versa) does it then work? And if you swap them, it doesn't work?

And, just in case you know (no need to try if you don't): do you think it's new with 3.2.10(.1) ?

(I set it to duplicate, but that's just for internal purposes)

I fixed this one just a week ago. You can checkout latest development version (hg clone http://hg.unrealircd.org/unreal).
If this didn't help, then let us know by posting a comment / reopening this issue.

And I agree it's important fix, it just happened that several users experienced this, yet nobody reported it (well you did ;p).

Thanks!
