Hi all,

I had done some work on ipfwadm on 2.0.X kernels.
It seems that this doesnt work in newer ones and ipchains have to be used
instead.

Re this, I would like the feedback on what is the appropriate tools
(ipchains/fwtk/...?) for setting up a firewall as per the requirement
below.

* There has to be a server which is on the Internet and has 2 cards - one
serving the local machines
* The mail/web/proxy/file servers have to be inside
* Access from outside has to be restricted on port/IP-address
* Redirection has to be done to the appropriate inside server/service
based on the destination address/port received.

TIA
