natd[330]: failed to write packet back (Permission denied)
Hi folks. natd[330]: failed to write packet back (Permission denied) I've started seeing this message in /var/log/messages recently on one gateway server, and it is rather frequent, recurring about 4 times every minute. Obviously I am running ipfw and natd, and my ipfw ruleset does include use of some dummynet pipes. Also, the box in question is still on 4.3-RELEASE, so if this is fixable by updating then that's what I'll do. Can anyone clue me in on the cause and perhaps a solution?

Hi, This happens when natd cant send a packet back to a host. Nothing really to worry about. If it is happening all the time then start worrying. Could you give a display of your ipfw ruleset ??

Could you give a display of your ipfw ruleset ?? Thanks for replying Doron. Could it be that natd returns the packet to ipfw, and the ruleset has a deny further down? Since the advent of Bugbear-B thre has been a lot of incoming netbious stuff (which I block, but only after natd has had a go at the packet). Perhaps this is the cause? Anyway, this particular server's ruleset has grown organically over about 2 years, so it is rather a mess. I think I need to give it a spring clean, remove the crud, and see how it behaves. I'll come back if I'm still having this problem after that. Thanks again, Regards, Patrick. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
