Hi,

I have installed two para-virtualized guests on the a RHEL 5.1 host. I met an issue of connection between each guest:

(1) Yes. Each guest could ping each other;

(2) No. Each guest couldn't SSH each other even I opened the SSH 22 port:
# iptables -L
ACCEPT   tcp -- anywhere         anywhere        tcp dpt:ssh


(3) No. Each guest also couldn't telnet each other:
guest1# telnet guest2
Trying 198.17.34.12...
telnet: connect to address 198.17.34.12: No route to host
telnet: Unable to connect to remote host: No route to host

(4) If I stopped the iptables on the both guests, then I could SSH or telnet between guests.

Did anyone know how to set the iptables rules on the para-virtualized host or guests to resolve it?

Thanks,
Winty
