remote build of Debian router

[Mike M <no-linux-support@earthlink.net>]

Hi,

Yesterday I built a Debian stable file server for my father assuming he
had a router/switch with a DHCP server on it.  Today I learned that he
does not have a router - only a switch.

I want to try making the Debian box into a router remotely. Would this work?

1) connect Deb box to cable modem
2) ssh to Deb box to test access
3) have father install 2nd NIC on Deb box
4) using ssh, install iptables and configure iptables on Deb box
