Hi all,
I'm running xen on gentoo since few months without problems. I recently installed shorewall (firewall) on domU. This domain has 3 network interfaces. One (eth1) is connected to internet through a cable modem. other are dmz (eth2) and internal network (eth0). I configured shorewall to accept and nat http connections from net zone (internet) to my smtp gateway in DMZ. These kind of connections doesn't work with xen. I ran ethereal on my laptop which simulated http requests from eth1 subnet and I found that tcp packets (replies) sent by the firewall have checksums errors.
Then I checked in bugzilla and found a patch for a similar bug(447). Source code seems to be correct regarding this patch. The linux kernel is : linux 2.6.12.6, xen version 3.0.1, gentoo package : xen-sources-2.6.12.6-r3 (02 Mar 2006)
Any ideas ?
Thanks
Jean-Luc
