[Solved] Problem with external connections to ejabberd server

I have an Ubuntu 10.04 server, running ejabberd 2.1.5. I installed it via apt-get ejabberd. The only options I changed in the ejabberd.cfg are the admin user and the host which is {hosts, ["mediabox"]}.

The host name of the server itself is also mediabox (avahi advertises it as mediabox.local). LAN users can connect fine, user@mediabox, but I cannot get any external connections to work. I used to run openfire on the same server and forwarded port 5222 to its IP address 192.168.1.77 and this worked. I have a dynamic dns account set up to point domain.dyndns.tv to my external IP address also.

my /etc/hosts file currently reads

127.0.0.1 localhost
127.0.1.1 mediabox

I have tried adding

192.168.1.77 mediabox
mediabox 192.168.1.77

but no combination of names in the hosts file works.

Any help would be much appreciated.

Also when I've tried connecting with Pidgin, this is the output from the debug window (addresses and IPs changed)
