Hi!

All the below mentioned works. I think you should use ipf for packet
filtering, and ipnat for NAT.

For /etc/ipnat.rules, the basic is:
map $inet_iface $lan_mask -> 0/32
$lan_mask= x.x.x.x/y (netmask)

For /etc/ipf.rules:

With many examples and tricks also.

Hi!

I am thinking to change my old linux router to the freebsd one. The
question is: how difficult is to convert iptables into ipfw rules?
I need some basic things with that router:
- internet gateway for LAN users
- packet filtering with MAC/IP address filtering
- port forwarding
- NAT onto same network so that LAN users can access web server which is
on the LAN also

Is this all possible with ipfw?

Regards,
Sasa
