Cisco ASA 5505 work with AT&T DSL PPP0E?

Does anyone know if you can use a Cisco 5505 with AT&T DSL? I was told that if I put the 2wire DSL modem into Bridge mode, that it should work using PPPoE on the Cisco 5505. AT&T is telling me that it won't work and that VPN is not supported

It works. Once you put your modem in bridge mode, you should be able to configure the outside interface to get an address (because ATT will assign you one).

On the outside interface, you should be able to do something like:

ip address dhcp setroute

The setroute keyword will set the default gateway for you. You'll need to set up your vpdn group for your username and password to be able to log in with your account information.

I used the wizard (GUI) on my first attempt to set the outside interface. Anything I should know about that, like that its not a complete setup?

If you are receving a dynamic ip address from att

=====

vpdn group INTERNET request dialout pppoe

vpdn group INTERNET ppp authentication {chap|mschap|pap}

vpdn group INTERNET localname

vpdn username password

!

! Apply VPDN to Outside interface, which is usually Vlan 2

interface Vlan 2

no ip address

ip address pppoe setroute

pppoe client vpdn group INTERNET

!

mtu outside 1492

!

=====

If static ip address:

!

vpdn group INTERNET request dialout pppoe

vpdn group INTERNET ppp authentication {chap|mschap|pap}

vpdn group INTERNET localname

vpdn username password

!

! Apply VPDN to Outside interface, which is usually Vlan 2

interface Vlan 2

no ip address

ip address setroute

pppoe client vpdn group INTERNET

!

mtu outside 1492

!

=====

Note that you should get all the ifnormation from the isp.

Username password and authendication method.

Hope this helps.
