We currently have an ASA5505 programmed as a static IP on a broadband connection.  It is all configured with VPN's to various sites, etc.

We purchased a metro E-line from ATT and found that the ASA 5505 does not support the VLAN setup because it cannnot encapsulate 1Q.  So, we have a Cisco 1841 on the way to create this bridge.

I'm sure this is simple...but I'm a rookie.  Could somebody supply quickly the configuration to setup 0/0 as the Metro eline and bridge all traffic to the 0/1 port, to which we would connect to the existing outside port of the ASA?  Assume outside IP is 83.83.28.23, gateway 83.83.28.22, vlan 45 for the Metro Eline info.

As far as inside routing assignment between 0/1 and the ASA, please assign...

Actually, the ASA can only encap dot1q for vlan support. You just need the appropriate feature license that supports DMZ vlan
