+Yes, unfortunately it wasn't as easy as I thought because the calling scheme inside IO::Socket::* (i.e. new -> configure -> connect ) isn't that simple if you have a class hierarchy and also try to implement multi-homing :(
+
+But I think I have a working patch (included, against 0.30).
+The basic idea of the patch is that one has to distinguish between an error at the transport layer which can be solved with IP based multi-homing and an error at the application layer. One could expect the system error to be reflected inside $!, while an application error will probably not set $! (e.g. IO::Socket::SSL sets an $SSL_ERROR variable). So if connect fails, but $! is not set, one can assume error at the application layer and stop trying to fix it with IP based multi-homing.
+
+The other difference in the patch is to change $self->IO::Socket::IP::connect($addr) to CORE::connect($self,$addr), because if you have a look at the connect function it simple calls CORE::connect if an $addr argument is given. It was already right to not use $self->connect in this place, it was only a problem if called from inside the new - configure - connect chain.
+
+With this patch the tests inside IO::Socket::IP pass and also the tests of IO::Socket::SSL.
+
+Regards,
+Steffen
