said by gb5102:You would configure 2 separate VPN Connections, one for each subnet, both using the same VPN Gateway.
Not quite as 'clean' as Cisco for example where you can have different subnets in an access-list, but it works the same in the end...
said by Brano:As already suggested, creating multiple tunnels is the solution.
Alternatively you could re-number your HQ networks and create one tunnel for larger range, for example:
Keep 192.168.0.0/24 renumber the other network to 192.168.1.0/24 and then you can create VPN tunnel for range 192.168.0.0 - 192.168.1.255.
Thank you both. The new VPN Connection with the other subnets was enstablished.
