    Trying to set up GRE here for routing a /29 to the house. I am using the
    following configuration and not sure what the problem is. I get a single
    packet through from the DSL box to the remote box then I get total packet
    loss. I can ping the 192.168.3.1 from 192.168.2.1 but not vis versa.
    If i assign an IP to my rl0 on the DSL box from the AssignedBlock it pings
    locally but not from the internet. In fact it bounces back and forth between
    the upstream's and my gre tunnel over which that block's assignment is
    handed. Totally unsure what I'm doing wrong here.

    Here's the setup:

    NOTE: AssignedBlock, LocalIP and RemoteIP are internet IP addresses/blocks per
    box.

    On DSL box:

    ifconfig gre1 create
    ifconfig gre1 192.168.3.1 192.168.2.1 link1
    ifconfig gre1 tunnel <LocalIP> <RemoteIP>
    route add -net XXX.XXX.XXX.137/29 192.168.2.1

    On remote box:

    ifconfig gre1 create
    ifconfig gre1 192.168.2.1 192.168.3.1 link1
    ifconfig gre1 tunnel <LocalIP> <RemoteIP>
    route add -net XXX.XXX.XXX.137/29 192.168.3.1
