I have rules like this (which skip after my ipv4 NAT rule where a accept all rule is): skipto 10000 ip4 from any to me 443 in recv em0 proto tcp limit src-addr 10 Altough after my upgrade, these packets don't get allowed out. When I change the rule to the below one it works just fine. skipto 10000 ip4 from any to me 443 in recv em0 proto tcp keep-state I see the dynamic rule getting installed with LIMIT: [/usr/src]$ sudo ipfw show -d |grep LIMIT 00000 2 120 (19s) LIMIT tcp 109.140.18.212 10087 <-> 141.135.72.71 443 :default 00000 3 180 (299s) LIMIT tcp 109.140.18.212 10087 <-> 141.135.72.71 443 :default 00000 3 180 (296s) LIMIT tcp 109.140.18.212 10087 <-> 141.135.72.71 443 :default Although I see the returning packets getting denied: Mar 5 20:23:13 vados kernel: ipfw: 9999 Deny TCP 141.135.72.71:443 109.140.18.212:10087 out via em0 Mar 5 20:23:16 vados kernel: ipfw: 9999 Deny TCP 141.135.72.71:443 109.140.18.212:10087 out via em0 Mar 5 20:23:19 vados kernel: ipfw: 9999 Deny TCP 141.135.72.71:443 109.140.18.212:10087 out via em0 Mar 5 20:23:22 vados kernel: ipfw: 9999 Deny TCP 141.135.72.71:443 109.140.18.212:10087 out via em0 Can somebody help me out with this?
