Re: PPPoA and bridging DSL modems

Hi,

Do you know if it is possible to bridge a modem doing PPPoA to a router
that supports PPPoE? Will the modem pass the authentication
information along?

I will be working with an Actiontec GT701-wg DSL modem and a Sonicwall
TZ170. The Sonicwall can do PPPoE but the DSL account will be DHCP and
PPPoA. I want the Sonicwall's external interface to be assigned the
public IP. Is this doable?

Thanks,
Dave

You cannot bridge oA to any router. What you can do is use the oA on the Actiontec and then tie off to the Sonicwall WAN port with no NAT. Set up rules as appropriate.

Unless this is a business, that is overkill. Are you hosting any servers? If not, just use NAT. Any hacker would have to hack your WAN management on the Actiontec (if there is any) in order to gain access. Your biggest security hole is when you start hosting servers and allowing people access to internal resources.
