-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've been using Linux and know iptables well, but I don't know ipfw although I had been using FreeBSD for 3 years good old days w/o firewall with dial up connection ;) So here goes my question. I am building a FreeBSD gateway at home. It obtains an external IP address from ISP dynamically using dhcp and I have two other boxes (and some virtual boxes) internally using static private network addresses (192.168.x.x). I want to set up a firewall/nat so that 1. The gateway (also a web server) accepts tcp port 80 and (probably) 25 from outside. but incoming tcp/udp ports 1-1024,1043,10000 connections are blocked. 2. Inside private network, nothing is blocked. Isn't it so simple? But I cannot find any nice examples...the default rc.firewall contains examples using the static ip address, but not DHCP. I want to specify the interface not ip address. BTW my external interface is rl0 (dhcp) and the internal one is fxp0 (static).
