Terminate PPPOE within cisco router or ASA 5505 (Double NAt)

johnsonjb — Mon, 11 Mar 2019 11:06:44 GMT

Hello

I am currently terminating my ISP's PPPoE connection (static IP) on my Cisco Soho77, and then using an internal IP on my firewalls outside interface and therefore double natting. I dont have a problem with this (makes me feel moer secure) but was just wanting some expert opinions regarding this since the ASA 5505 has the option to terminate the PPPoE session as well (then I could just do bridging on the Outside router. Any suggestions or thoughts would be great. I am also running a web server on the DMZ.

Thanks in advance

Jeff

You can also enable PPPoE by manually entering the IP address, using the ip address command from interface configuration mode in the following format:

hostname(config-if)# ip address ipaddress mask pppoe
