The easiest way to do IP masquerade is with shorewall.  Try the two

Hi Chris, I took a look into shorewall. I followed the information to setup a simple Xen system. But it doesn't work. I can't connect to the web-server. I always get a "conneciton refused".

Here is some output from the logging and TCPDUMP:

HTTP from DMZ/ (wget www.robertmuench.de)

Here I tracked a wget So the requests comes in but is immediatly answered with something that rejects/refuses the connection to be established. Error message on the requester: connection refused.

root@eisxen:~/shorewall-config# tcpdump -i eth0 host and port 80

In which mode do I need to run XEN, bridged, routed, nat? I have tried birdged and nat. Same effect, doesn't work.

Best regards.
