I have the following rule added with ipfw: 230 Deny log udp from any to 194.121.229.32/28 111 via sl0 This rule should drop udp packets to the sunrpc port coming in via interface sl0. But instead it seems to deny random udp traffic to my network: Sep 4 16:13:09 gw-deadnet : /kernel: ipfw: 230 Deny UDP 130.83.22.1:17993 194.121.229.34:17732 in via sl0 Fragment = 123 This packet was dropped, although it is not directed to the sunrpc port. Am I missing something, or is this definately a BUG? Regards, Mickey -- (__) (@@) Andreas S.
