Branch Office Internet Access

    Im having a problem allowing a branch office to access the Internet
    through our main office T1 line. I've had 2 different techs out here
    who say they can't figure out why our branch office can not access the
    internet. So I hope someone here can point me in the right direction.

    Our Main office (192.168.1.0 subnet) has a firewall to the intenet
    with an address of 192.168.1.254 this is the default gateway for the
    main office. The firewall also has a routing table in it to our
    branch office. The main office has a Cisco 1600 (old I know) with a ip
    address (Ethernet0) 192.168.1.24 that connects to our branch Office
    router over the T1 using Serial0 and network 192.168.254.21.

    Our Branch office (192.168.2.0 subnet) connects to the main office
    using serial0 192.168.254.22 with Ethernet0 192.168.2.21 the default
    route for users in the branch office.

    From the main office I can ping and access the resources in the
    192.168.2.0 subnet and from the branch office I can ping and access
    all resources in the 192.168.1.0 subnet (including the firewall). The
    only thing the brach office can not access is the Internet. If I ping
    an Internet address from a computer at the remote office I get Reply
    from 192.168.254.21 :Destination host unreachable. Sounds like a
    routing issue to me but I am unsure where to look or what to change on
    the Cisco.

    Our basic layout is:
    Main Office:

    Firewall(192.168.1.254) <-> (192.168.1.0)

    Main Cisco 1600 192.168.1.24
    192.168.254.21 <--> T1 <--> 192.168.254.22
    192.168.2.21 Branch Cisco
    1600

    ------------------------------------------
    The Main 1600 has no ip classless

    ------------------------------------------
    The Branch 1600 has no ip classless
    ip route 0.0.0.0 0.0.0.0 192.168.254.21

    Thanks in advance for any help

  2. Sounds like the main office 1600 needs a default route, pointing to
    the firewall's IP address. (It's odd that you get 'host unreachable'
    instead of 'network unreachable', though.)
