[vpn-help] problems setting up VPN network

[Matt Patey]

Hi,

I am trying to set up a VPN connection to my home LAN. I can
successfully establish the tunnel, but cannot ping any of the computers
on the remote LAN and my internet connection is not routed through the
tunnel and I suspect I have a routing problem. If anyone can tell me what
I'm doing wrong or point me in the right direction I would be very grateful.

I am connecting to a Netgear Prosafe SRXN3205 VPN firewall from a Linux
Mint 13, 64bit client. I compiled version 2.2.0-rc2 of the client (due
to an issue with the packaged version in the Ubuntu repositories that
means it doesn't work). I have followed this guide closely:

http://www.shrew.net/support/Howto_Netgear

The subnets involved are:

192.168.1.0/24 - remote (host) LAN (behind Netgear router)
192.168.0.0/24 - client LAN
10.2.25.0/24 - address range assigned to VPN clients

Once the tunnel is established my computer's routing table is as follows
(the 2nd and 3rd entries were added by the shrew client):

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask        Flags Metric Ref Use Iface
0.0.0.0           192.168.0.1  0.0.0.0               UG    0     0   0   wlan0
10.2.25.0        0.0.0.0         255.255.255.0    U      0      0   0   tap0
[NG public IP] 192.168.0.1  255.255.255.255 UGH 0      0   0   wlan0
169.254.0.0     0.0.0.0        255.255.0.0        U      1000 0   0   wlan0
192.168.0.0     0.0.0.0        255.255.255.0     U      2      0   0   wlan0

The Netgear router's routing table looks like this (I added the 3rd line with a
manual route, but it still doesn't work):

Interface Name Destination        Mask                  Gateway    Metric
WAN-VIRTUAL 87.194.204.1    255.255.255.255    0.0.0.0        0
LAN                 192.168.1.0      255.255.255.0       0.0.0.0         0
LAN                 10.2.25.0          255.255.255.0       0.0.0.0         2
WAN-VIRTUAL 87.194.204.0     255.255.252.0       0.0.0.0         0
WAN-VIRTUAL default              0.0.0.0               87.194.204.1   0

Thanks for your attention!
