Check your ACL 103. . .
There's no permit statement for the 192.168.1.x block. It's referenced by your ip nat route-map statement.
That's all I see that's wrong, but I'm not overly hip on VPNs. I can set 'em up, but don't blow on them, or they'll probably crumble. lol
[edit]Oh, and just a suggestion. . .put "deny ip any any" at the end of ACLs. . .that way you can see what's not getting through, and how much is not getting through.
