[opensuse-virtual] Strange network problem: ping works, TCP doesn't

Yodel!
[cc:'s appreciated]
I'm a bit confused.
Bridged networking, no firewall, external host on the same network as the
Xen machine.
I can ping between external, domU and dom0 in all directions.
I can ssh between domU and dom0, and I can ssh between dom0 and external, in
both directions.
I can't ssh between domU and external at all. Or any other TCP based thing.
Connection opens (netstat shows an open connection), so some initial ACK
seems to go through, but after that the connection is dead.
ping works regardless of packet size, so it isn't an MTU issue. I assume
it's not a MAC issue as ping wouldn't work, right? I'm not sure where to
start looking.
(Oh, yes: everything is on SLES10)
cheers
