Trying to set up GRE here for routing a /29 to the house. I am using the=20
following configuration and not sure what the problem is. I get a single=20
packet through from the DSL box to the remote box then I get total packet=20
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=
=20
locally but not from the internet. In fact it bounces back and forth betwee=
n=20
the upstream's and my gre tunnel over which that block's assignment is=20
handed. Totally unsure what I'm doing wrong here.

Here's the setup:

NOTE: AssignedBlock, LocalIP and RemoteIP are internet IP addresses/blocks =
per=20
box.=20

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
