But when I route to ISPTWO gateway, only ISPTWO > connection can be seen!? what happening here is that ispone ip block is still routable for outgoing traffic going to isptwo(except if your isptwo or its ascendants implemented ingress filtering where to allow only to pass those ip addresses known to them and drop it otherwise).... upon returning (where the source ip address is now the destination ip address), it will pass thru to ispone and not to isptwo... in case you temporarily down your ispone link, you will not receive any packets coming from ispone segment block even if you change their default gateway to isptwo... fooler. _ Philippine Linux Users Group.
