Mandrake Multi Network Firewall MNF

[Engineer]

Has anyone tried out MNF from Mandrake? I just downloaded it the other day and am getting ready to install it/set it up. I was just wondering if it had capabilities to be a firewall/router or just a firewall if anyone knows? I am still searching for info but haven't found too much about routing, we need a router because our current one doesn't support port forwarding. If I set up RedHat as a firewall does it have routing capabilities also? and does it have a web interface configuration or some type of gui? I am also seriously considering Smoothwall as I have read a couple responses about MNF saying it was a little shaky to install/setup

Thanks
