The easiest thing to do (if safe to do so) would be to temporarily
switch off the firewall entirely. If it starts working, then that's
the reason! If you're using iptables, try:
sudo service iptables stop
...on both machines. If the problem persists, (and your firewall is
iptables), then the problem is elsewhere.
