How to configure branch site to use Host site internet using MLPPP connection

I have a main and branch site connected with MLPPP (2 T1's), on Netvanta 3448 routers with dual T1 nim cards. What I am trying to figure out is how my branch site will use the internet from the main site allowing us to cut the cost of an additional internet connection at branch site. I have the host site and branch sites connected with MLPPP but I am not sure how to set either NAT or next hop to internet at main site. I have included a diagram on this question but let me know if you need to see some configs. If anyone could maybe point me in the right direction it would be greatly appreciated. This is my first PPP, let alone MLPPP connection.

Post the config please. You can cut out any passwords, and the public ip address block.

Ok, here are the configs for branch and main. Since branch is supposed to use the internet from main I am not sure if it is as simple as adding a route or what, I admit I have not configured this scenario before. Thanks for all your help API NOC it is certainly appreciated.

Ok, everything worked great. All I needed to cahnge was the subnets for the ppp's. I actually had 172.16.22.1 and 172.16.21.1 and changed that to 22.1 and 22.2. Then I added the 0 0 192.168.2.0 and 1.0 routes and the 0 0 ppp1 and bam Internet worked and both sites had access to each other.

Thanks for your info it certainly worked great.

API NOC, could you look at my next question related to the same network? I am now trying to port forward identical ports to both servers at each site. Here is the link if you have time. Thanks again for all your help. The configs are working perfectly I just need to configure this last part.
