Typically, that sort of message indicates that the firewall rules are preventing traffic from going out, or packets are getting stuck in a queue until it fills up, or maybe even a bug somewhere in the particular combination of kernel firewall options enabled, high optimization or CPUTYPE settings, and your particular hardware, depending on how lucky you are. :-) Does the problem go away if you use a trivial "permit all" PF ruleset? Does the problem go away if you use a trivial IPFW "permit all" instead of PF? Does the problem go away if you use a stock 5.4 release kernel? The 3Com 3c905B-TX is an OK NIC, apparently the later C revision or the 918/920's are pretty decent, but anyway-- ...does the problem go away if you switch to another (known good) NIC? -- -Chuck
