If you are connecting using the point to point protocol (PPP) then user ppp has a configurable firewall built in. Type 'man ppp' for one of the best 'man' pages I've seen. Or: http://www.google.com/bsd?q=ppp+firewall&num=100&site=search&restrict=bsd&hl=en&safe=off&btnG=Google+Search For larger networks, a choice of ipfw or ipfilter is easily configurable by the addition of a few lines in a custom kernel. Deciding what rules you need and implementing them is neo-exciting. Charlie Schloemer mentioned the bpf (Berkeley Packet Filter). I think this is not necessary unless you need to snoop your network with tcpdump etc. I think there are security reasons for not enabling bpf. Especially for a firewall box. HTH John.
