Hello- I am pretty new to natd and ipfw, so i would like to be able to describe what i want to be able to do with my new bsd router. This is to understand the nomenclature and how understand how other people use bsd as a router/firewall. So far i have manually done this to my router. >sysctl net.inet.ip.forwarding=1 # gateway_enable="YES" >natd -interface rl1 >ipfw -f flush >ipfw add divert natd all from any to any via rl1 >ipfw add pass all from any to any notes: r11 is my external network rl0 is my internal network here is what i would like to do in a more standard way. Please correct my wording if it is off or if it unclear. port forward: ssh from a local machine port 22 to the router port 22, open to the outside port forward: vpn port 5001 for all local machines, open to the outside block all servers on the router to the outside, but not the inside anyone on the local network has access to services on the router what else should i consider? is port forwarding done with ip or with mac address? cheers, brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
