Once you hit a > 10.0.0.0 network outside of a local network, all bets are off... Actually, no. This is not true. Private addresses do show up on traceroutes quite often. It indicates a link in the route which is using private addresses for internal routing. You can't address it directly but when it returns an error (TTL expired) it indicates the address at which the failure occured. That failure just happen to be at one of those private addresses. You should never see one of those private addresses routed to or addressed to outside of your local address and boarder gateways SHOULD filter out anything that has a source address of a private address space, but, baring "policy routing", stock routing does not take the source address into consideration in the routing tables. Lack of filtering? Maybe... Debatable. Hopelessly messed up routing tables? Not. > -justin Mike -- Michael H.
