Hi Guys,
This is not really a cisco specific question. I just need some clarification on ADSL bridging. I have a situation where an ISP will deliver a /29 address block over an ADSL connection. I assume the ADSL connection will be PPPoA / PPPoE based. The ADSL router is a simple consumer grade product and a firewall will sit behind with a public IP address on an Ethernet interface within this /29 block. My question is if I have this /29 block how can the ADSL router be addressed LAN/WAN? I assume the only way to do this is to bridge the ADSL connection to the Ethernet network? If I bridge the connection does this mean the firewall will need to run the PPPoE/PPPoA protocol? I am confused as to where the encapsulation / de-encapsulation occurs with this type of design. The ADSL router or the firewall? Can I have the ADSL router take care of all the necessary PPP functions such as authentication etc with bridging? Can someone please shed some light? Thanks, -Aaron. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
