Yes, there's the Sockets module in the ghc library, which allows you
to do TCP and UDP (and more). I can show you some examples. Not sure
what you mean about firewalls, there is nothing that I am aware of to
do packet filtering and routing and the like. If you just want a
socket connection across a firewall, I'd just tunnel it through ssh.
