It somehow seems wrong that sshd would be trying to listen on 0.0.0.0. I suspect that (a) you specified an invalid ListenAddress in sshd_config or (b) you uncommented the "#ListenAddress 0.0.0.0" and "#ListenAddress ::" examples in the file without actually changing the addresses. (The latter is just a null IPv6 address.) It's usually best to leave it on the default setting (i.e. comment out ListenAddress), which is to listen on all local interfaces. OpenSSH has created a very secure daemon, and I doubt there is any justifiable security concern to warrant blocking logins from certain interfaces. If you've still got trouble, see if "ps -ax |grep sshd" turns up anything. If so, try to connect to the box locally. You could also try disabling the firewall temporarily, but I doubt that it is to blame. Just make sure you actually are loading a ruleset--- unless you changed it in the kernel configuration, the default is to deny everything.
