Linux behind a cisco router
Dear All,
I have worked with xDSL routers working in bridged mode, and linux behind them working as a Firewall utilizing IPTABLES. My question is, how this will change if the xDSL router is replaced with a Cisco Router? I mean to ask that, can I assign a public ip on the linux machine, which is behind the Cisco router? Do I have to do natting/port forwarding on the Router ? One ethernet on router is directly connected to linux machine. Can I utilize some packet analyzer or sniffer to find out what goes on during this type of communication? Thanks for taking your time to read this. _ ( ) ( Internet ) ( ) ___ | | |________ > (Cisco router)___________> (Linux box) Last edited by tmm; 01-30-2008 at 12:51 AM.
