How to configure bridge mode in NetVanta 3200 with 2 T1s

Adtran Experts. I have the following question and I really need help.

We are replacing old firewalls with embedded T1s with new firewalls with no T1s.

We have an MPLS circuit with a multilink T1s.

Per the vendor, I need to configure PPP.

The vendor has provided /30 IPs for my mpls circuit.

On my new firewall, I have assigned 192.168.0.10 IP on the MPLS interface with the next hop as the gateway.

Since I don't have enough IPs. I want to configure the Router as bridge mode.

So far this is the configuration I have created.

Can you tell if I am missing something or is there a better way to configure it. Do I need to configure a router for the gateway?
