I'm sorry. My English isn't very good. Did you right understand
what do these rules? I'll try a bit more describe they:
10164 allow ip from 184.108.40.206 to any uid net
This rule match all TCP or UDP packets from 220.127.116.11 to any, which
will be sent or received by processes witch works as user "net"
on your machine. E.g. you can run a web-server as user "net" and some
packets will be matched by this rule (if they will be from
18.104.22.168 to any).
10165 allow ip from any to 22.214.171.124
This rule match all IP packets from any addresses to 126.96.36.199.
10166 allow tcp from 188.8.131.52 10000-65535,21,22,25,80,110,113,443
This rule will be match packets for source address 184.108.40.206 and
source ports 10000-65535,21,22,25,80,110,113,443 destined to any
addresses and ports. It will not match packets if they already
matched by rule 10164, because "allow" action terminates search.
10167 deny ip from 220.127.116.11 to any
This rule will deny packets that didn't match rules 10164 and 10166.
Did you want the same?
WBR, Andrey V. Elsukov
