Yes I can see the traffic coming back when I do a tcpdump... you can see 172.69.128.107 access 74.125.79.104.http and then 74.125.79.104.http talks back to 172.69.128.107 , now this is encapsulated in a GRE tunnel as my alt interface is a GRE tunnel but it works for the local box.. as per my previous post a couple days ago... below is the sample of the tcpdump, 18:26:21.722567 IP 172.69.128.98 >
