Can you run tcpdump on the new router? Have you run tcpdump on your FreeBSD boxes to see where things are going? What you wrote sounds like you are speculating about some aspects of the situation. If you can trace where they go and how far they go you can present a much clearer question. If the return packets do go through your new router what are the addresses in the header once they get to the far side of the router (i.e. on the outbound interface) If the 'to' address is correct and the 'from' address is the router itself then the point where they are getting blocked might be at the far end. Could the host that is expecting the reply be blocking or ignoring the reply packets because the 'from' address is different than what is expected? ----- Original Message ----- From: Bruce Piper <bruce_piper@hotmail.com> To: <freebsd-questions@freebsd.org> Sent: Friday, March 09, 2001 5:29 AM Subject: Routing question > Hi there > I have just added a second router to my network.
