Cisco Router Point to Point problem

All,

I have 2 Sites running a point to point connection right now.  The scheme is 172.16.x.x.  The router at the main site is able to ping the Ethernet and Serial interface of the Cisco router at the other site, as well as all the workstations at the other site.  From the other site, workstations are able to ping the ethernet, serial 0 and serial 1 interfaces of the router at the main site.  At the main site, Serial 1 is the interface that the T1 connects to for delivering the internet connection.  All users at the main site are able to get out to the web, receive e-mail.  From outside the network, I am able to RDP and VPN into the main site's server.  I just can't figure out why everyone at the remote site is able to ping everything on the network, as well as the IP on Serial1, but cannot ping outside IP's and cannot reach the web.  Just for fun, I was able to connect from a workstation at the remote site via vpn to the site here to get out to the web, it worked fine.  Here is the configs of the remote router and the main router, if someone could point out what is going wrong, I would appreciate it.

Make the following change on the Router at the main site

config term
interface Serial0
ip nat inside

Right now, you only have "ip nat inside" on the ethernet interface, when you add it under Serial 0, it will allow remote users to access the internet.
