Can I bridge a cisco router off to a linux server?
Posted on 2010-09-15
We have a scenario where we must "bridge" a cisco router to the linux server on the LAN as we want the linux server to get the public IP. The thing is, we like the debugging tool on the cisco router when it comes to PPOE/PPOA connections with the ISP (yes our ISP still uses username and passwords).
The problem is, of course, that using the PPOE command on the router means that the dialer interface gets the CPE address from the ISP, that means that I cant use those public addresses on the connecting port of the linux server.
Is there a way of connecting to the ISP on cisco router with PPOE and still bridge the router so that the linux server uses the CPE address?
Or must I essentially turn the linux into a DMZ zone on a different public subnet and use the CPE as a firewall?
