Hey guys (and gals!), I'm hitting what seems to be a bug on PF @ FreeBSD 6-stable: 6.0-STABLE FreeBSD 6.0-STABLE #0: Sun Nov 20 05:14:34 WET 2005 If I do a pfct -vvsS | grep connetions I get some lines like this: 10.10.11.208 -> 0.0.0.0 ( states 3, connections 4294967295, rate 0.0/0s ) 10.10.13.213 -> 0.0.0.0 ( states 2, connections 4294967294, rate 0.0/0s ) 10.10.14.236 -> 0.0.0.0 ( states 96, connections 4294967013, rate 0.0/0s ) 10.10.12.238 -> 0.0.0.0 ( states 9, connections 4294967281, rate 0.0/0s ) I also get a normal number of connections, like 2, 10, 20, 30, etc. Now, this number is completely insane, specially if we take into account the rule that creates it: ala# pfctl -vvsS |grep 10.10.11.208 -A1 10.10.11.208 -> 0.0.0.0 ( states 1, connections 1, rate 0.0/0s ) age 02:22:00, 657 pkts, 39752 bytes, filter rule 171 -- 10.10.11.208 -> 0.0.0.0 ( states 1, connections 4294967295, rate 0.0/0s ) age 02:22:15, 618 pkts, 52535 bytes, filter rule 148 ala# pfctl -vvsr |grep @148 -A1 @148 pass in log on fxp0 from <torre_privados_nat:7> to any keep state (max 5000, source-track rule, max-src-states 120, max-src-conn 100) queue p2p [ Evaluations: 43699 Packets: 353469 Bytes: 122287213 States: 210 ] I have been seeing this on rules in which I use max-src-conn but not on others. So, what might be happening here? hasn't no one seen this before? Also notice how similar the connections are, with the first 7 numbers equal. BA
