    First off i can tell you that i have no experience with setting up vpn
    connections. Now that i got that out... Im trying to configure 2 x
    Cisco PIX 501
    firewalls to create a vpn-tunnel from 2 seperate locations. So that i
    can access both internal networks from either location. So far i have
    managed to setup a tunnel wich kinda works. Both the IKE and IPSEC
    tunnels are up and working.. but i cannot reach the internal networks
    on the inside of either pix.

    This is getting very frustrating.. so if someone can lend me a hand i
    would jump for joy! :)

    Added a stripped dump of configuration on PIX number 2. Since both
    PIX's use the same config except changes in IP addresses i only
    included config for one of them.

    remove the:

    isakmp enable inside

    You only enable it on the OUTSIDE interface.
