Cannot access lan(s)

[MChrisM]

Hello --
I have two networks -- (206.187.186.xxx 0.255.255.255 & 172.17.170.xxx 0.0.255.255) these are connected via a dedicated T1 (metro private line) I cna ping both the outside and inside adapters on my 1720 routers but cannot access the networks beyond the inside adapters. I want to be able to FTP and run a sync utility accross this T1 connection I would really just like to open the router up with no port restrictions or anything.
here is how the connections are set up

206.187.186.xxx 0.255.255.255 (home network)
======
206.187.186.36 (inside adapter on router 1)
67.64.194.120/28 (outside adapter on router 1)
======

63.208.48.121/25 (outside adapter on router 2)
172.17.170.36 (inside adapter on router 2)
======

172.17.170.xxx 0.0.255.255 (remote dr network)

now I can ping all of the adapters and ping the internal networks from the respective router i.e. ping the 172 net work from router 2 and ping the 206 network from router 1 but i cannot ping the 172 network from router 1 nor the 206 network from router 2.

here are my router configs

Any help would be great I know I must be missing something that is totally obvious but I am just not seeing it --

Thanks !!!!!
