Hi all. I wrote to the list the day Monday, but does not explain the problem well. I have a proxy server that is transparent, working with wccp, I have a router that send to the server the request of port 80 and this gives back the results. The company adquired a new connection, and this especify connection is for 2 networks, now what I want is that those two networks leave by the new connection. This I have it to do from the server, the server has two connected interfaces each one to a connection. All the input requests is by an interface (ETH0), the use of other interface is only when the server detects that the address used the other interface (ETH1). My scheme is: | ------- 200.9.189.201 ----------- | router| ----------------------------| Switch | ------- 165.98.111.233 ----------- | | (INPUT-OUTPUT) --> | | <--(OUTPUT) If-eth0 If-eth1 | | ------------- |server proxy | -------------- Some body can help me? Thanks in Advanced, Regards,
