VPN Multipul IP Ranges / Subnets was created by andy@coops.org.uk
Hi

We have 2 IP Subnets at our Host site but can only contact to 1 IP Range via our Lan-Lan VPN with a Vigor 2820 at each end.

To try to explain:

Remote site:
Subnet 10.0.0.*

Host Site:
Servers have 2 LAN Adaptors, only 1 server adaptor is plugged into the 2820, this is using the IP Range: 192.168.0.*
The Servers LAN cards and remainder of the LAN run off another IP Range of: 192.168.100.*

We need our remote site to access machines on the 192.168.100.* range.
Is it possible to make the 2820s aware of this IP range despite only being connected via multihomed servers?

We can talk to Machines over the VPN on the 192.168.0.* range, but not the 192.168.100.*

Thanks
Andy

In the LAN to LAN VPN profile, go to section 4 and click the More button, in there you can enter the 192.168.100.0/255.255.255.0 range, that'll make the VPN end aware that that network is through the VPN.

For the router on the local end to be aware of the other subnet, you'll need to make a static route (under LAN and Static route) if you haven't already with the server's LAN IP as the gateway.

Voodle - I've tried your suggestion but am still struggling.

The host (multihomed) site I've added the static toute to 192.168.100.0 with the servers LAN IP as the gateway and at our remote site in the LAN to LAN profile I've added the 192.168.100.0 range via the more button.

from the remote end I still can't talk to anything on the 192.168.100.0 range.

any ideas? have I done something wrong?

Is the router on the 192.168.0.* range able to "talk" to the 192.168.100.* network? You can check this from Diagnosis and Ping Diagnostics, just enter an IP address of something on that network in there and see if it can ping it or not.

not the router cannot ping the 192.168.100.0 range
is this likely to be a routing issue on the multihomed server
