Well, now you've isolated the problem. That's a *huge* step! I've seen 
various recipes to configure Xen and iptables, but not seen a clean and 
intelligible one: I've seen what is clearly a lot of gobbledy gook 
written by script kiddies doing cut&paste. So I've used external 
firewalls rather than spending the time to hand-brew my own.
That'll have to change for me soon. I'd welcome good pointers to good 
write-ups to set it correctly.
