I posted this on freebsd-questions last week & unfortunately the folks who rsvp'd did not have a solution so I've posted to this forum. I'm having a problem with IPF blocking packets that appear should be let through. I've sent quite a bit of time going through the Handbook, man pages, etc & I must be missing something so any help is greatly appriciated. uname -a freebsd 4.11-release #0 SMP kernel, dual PIII processor, 512 MB ECC RAM, SCSI HDs execerpt from rule set: Kernel compiled with "default allow" until I finish getting the rule set rewritten. Rule #1 block in log from any to any pass in quick on lo0 pass out quick on lo0 block in log quick on fxp0 from any to any with ipopts block in log quick proto tcp from any to any with short ... pass in log first proto tcp from any to any port = 80 flags S keep state pass in log first proto tcp from any port = 80 to any flags S keep state pass out log first proto tcp from any to any port = 80 flags S keep state netstat -m = 129/576/16384 9% of mb_map in use Proxy Server - Squid 2.5.stable10 The behavior I'm seeing is out going connections to websites on port 80 are being passed but the in bound traffic is being blocked. The ipflog entries look like this: my ip = s theirs = d @0:390 p s.s.s.s,3601 -> d.d.d.d,80 PR tcp len 20 60 -S K-S OUT @0:1 b d.d.d.d,80 -> s.s.s.s,3601 PR tcp len 20 43 -AR IN Thanks in advance to those giving their time to lend a hand, I know you time is valuable.
