If you've got the following setup: ------- ------------- -------- 'net---| Box A |-- LAN --| Box B (ppp) |-----| Client | ------- ------------- -------- You need to run the aliasing software on the 'net side of Box A and = make sure that Box A knows how to route to Client via Box B (10/24) = so that it makes everything look like it comes from itself when it = transmits to the 'net and so that it knows what to do with the = replies when it gets them back. My suspicion was that Box A didn't know how to route to Client via = Box B. If Box A can talk directly to Client, and Box A runs either natd or = ppp -alias on it's 'net interface, there should be no problem. > -- > WBW Andy V.
