Yes. It should work. This is what I meant by " If ip_forward is 0, you cannot ping >> systems in the 192 network other than the host having the two cards." A ---------------------------------- B ------------------- C 172.x.y.z 172.x.y.1 192.a.b.1 192.a.b.c I'm assuming this is what you've and ip_forward is 0 on B. You are pinging 192.a.b.1 from A. It should work as the host B responds to the ping and not the interface. Always the case... In common parlance, we use the term ping the interface. In reality it is ping the host thro' the interface. If ip_forward is 0, A cannot ping C. -- Mohan Sundaram _______________________________________________ To unsubscribe, email ilugc-requ...@ae.iitm.ac.in with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
