ISSUE
I have, after some days of "hard" work, managed to correctly configure kvm on a Centos 5.5 host. I have 2 VM running successfully. Since I only have one public IP address (for the kvm host) I am trying to setup port forwarding (using IP tables). And everything seems to work fine. When I rdp to 'hostname.com:3389' I successfully get the login screen for my Windows XP VM.
The problem starts after logging in... As soon as I provided my credentials in the Windows XP VM the rdp session disconnect/reconnects... It all happens so fast that I cannot really do anything (in a matter of seconds I am disconnected and reconnected again).
TROUBLESHOOTING
So what have I already tried/checked? 1. I tested the port forwarding the other VM (a Centos system) and I can successfully connect using ssh (and no disconnects). 2. I checked that after I created the iptables rules I could still access the host and the Internet from my Windows XP VM.
LOGS/OUTPUT
PREROUTING rule:
DNAT tcp -- 0.0.0.0/0 12.12.12.12 tcp dpt:21 to:192.168.122.1:3389
FORWARD rule:
ACCEPT all -- anywhere 192.168.122.0/24 state NEW,RELATED,ESTABLISHED
To me this all should work... Unfortunately it does not! Hope somebody can help me!
