I'm so far very pleased with m0n0wall, but couldn't find out this thing.
I've successfully established an IPSEC tunnel from our 10/8 net to
another 192.168.x/24 net over the internet. Sending a ping from m0n0wall
directly to a machine in the tunneled 192 net works, but I'm unable to
find out how I can from any machine withing 10/8 access the 192.168.x/24
When I ping from 10/8 to a machine in 192.168.x./24 the ping reaches the
default gateway of m0n0wall which is the gateway of my provider so I
think I've to somehow tell m0n0wall "all requests from my lan (10/8) to
the subnet 192.168.x/24 should be sent over the tunnel". Unfortunately I
can't work out the "should be sent over the tunnel" part. I guess I need
to set a route somewhere, but I don't know if I need a static route, a
outband NAT route, etc.
Here's a short overview of the network
LAN (10/8) - m0n0wall - Internet - other tunnel endpoint - 192.168.x/24
Ping works from m0n0wall -> 192.168.x/24 but not from LAN (10/8) ->
192.168.x/24. Or any other TCP service.
Any help is very appreciated,
