Hi Guys

I am in need of someone to bounce this issue off of...I am pretty sure that I am being silly

Router 1 holds a public /24

Router 2 on a /32 public ip, different ISP all together...PPPoE connection

IPIP tunnel between the two routers on a /30

IPIP tunnel is up and working fine, routers can ping each other as expected.

Route one routes a public /30 to Router 2 over the IPIP link, obviously the IPIP link is not the default route out on Router 2; so i've route marked all traffic coming in on the IPIP link to route back out via a default route in a seperate routing table - this then allows ping to pass correctly, but no other traffic.

I am missing something really simple here, outbound packets needs to have the SRC IP address from the /30

Thanks in advance
Mark
