Re: [Xen-users] 3.0.2 NAT headaches

["John Wells" <groups@xxxxxxxxxxxxxxxxxxxxx>]

Someone noted that I wasn't receiving a reply from the host I was pinging
on eth0. That appears to be the case...I'm seeing replies on peth0, but
they never make it to eth0. Here's peth0:

/etc/xen# tcpdump -ni peth0 port ! 22 and host 72.36.190.2
16:02:42.104599 IP 72.232.35.26 > 72.36.190.2: icmp 64: echo request seq 181
16:02:42.105137 IP 72.36.190.2 > 72.232.35.26: icmp 64: echo reply seq 181
16:02:43.104515 IP 72.232.35.26 > 72.36.190.2: icmp 64: echo request seq 182
16:02:43.105164 IP 72.36.190.2 > 72.232.35.26: icmp 64: echo reply seq 182

and here's eth0:
/etc/xen# tcpdump -ni peth0 port ! 22 and host 72.36.190.2
16:02:42.104599 IP 72.232.35.26 > 72.36.190.2: icmp 64: echo request seq 181
16:02:42.105137 IP 72.36.190.2 > 72.232.35.26: icmp 64: echo reply seq 181
16:02:43.104515 IP 72.232.35.26 > 72.36.190.2: icmp 64: echo request seq 182
16:02:43.105164 IP 72.36.190.2 > 72.232.35.26: icmp 64: echo reply seq 182

Additionally, I do indeed have ip_forward enabled:
/etc/xen# cat /proc/sys/net/ipv4/ip_forward
1

Any ideas what I'm missing?

Thanks,
John
