Configs look valid, try the follwoing

no ip nat pool branch netmask

ip nat inside source route-map nonat interface f0/0 overload

no ip nat inside source route-map nonat pool branch overload

Run the following debugs in router, then initiate an interesting traffic and paste the debug output

debug crypto ipsec

debug crypto isakmp
