 When I comment out 400 and 500 rules and add allow all from any to any via
 rl1 it's all ok. The problem is somewhere in 400 and 500 rules.

Those lines (400 and 500) sure look like they could cause trouble. Try
chopping them up per port number/range across multiple lines.

ipfw and natd are nice for the quick-and-dirty setups, but if you need
something more predictable, configurable, and debuggableswitch to
ipfilter and ipnat. You'll find yourself very much in control over your
firewall/nat environment.

I tried to allow only 80 port, but the result is the same. I have also tried
ipf + ipnat, but i need to block internet connection to some users by MAC
address, and ipf doesn't know, what MAC address is. Maybe i can block MAC
addresses with ipf + ipnat somehow? Btw FreeBSD version is 4.9.
