I would like to put my ADSL modem/router into bridging mode and have my PIX 501 accept the single public IP. Would the ADSL modem or the PIX firewall do the PPPoE authenication? If the PIX has to do the PPPoE then I would just have to worry about the vpdn statements and make sure the outside interface of the PIX reflects the public IP address. Its a static address so I can just manually enter it in. Am I on the right track and can anyone point me towards an example config?
