I think I implemented something similar to what you want to accomplish. I put the wireless router behind my gateway (a NetBSD box) and used IP redirection to override the router's hardcoded attempts to connect to an external NTP server. It was rather straightforward. I set up some ipf rules to accept and log outgoing requests on UDP port 123, then used ipmon to capture the information and figure out the address the wireless router attempts to connect to. Then, I put the following line in /etc/ipnat.conf: rdr re1 209.81.9.7/32 port 123 -> 127.0.0.1 port 123 udp With this configuration, my wireless router no longer connects to the outside world. My own gateway's NTP server provides the answers. -- Pierre Dubuc [EMAIL PROTECTED] _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
