Have a Draytek 2860 router with an IPSEC VPN connection to a Cisco router in a data centre.
There are 3 local subnets setup on the router that need to access the VPN tunnel - 192.168.10.0/24, 192.168.11.0/24 and 192.168.13.0/24
There is a single subnet at the Cisco end. 192.168.10.0/24 is setup as the Draytek's local network ID in the VPN settings.
I can ping hosts on the Cisco subnet from hosts on 192.168.10.0/24, but nothing responds when using 11.0 and 13.0.
Doing trace routes I can see that traffic from the different subnets is going out through the three different router IPS - 10.1, 11.1 and 13.1.
As 11.1 and 13.1 are interfaces on the same box as 10.1 and there's a routing table entry to the Cisco's subnet, I can't understand why traffic isn't being routed through the VPN.
Have tried adding a route policy to force anything with a destination IP on the Cisco's subnet to be sent down the VPN - but that had no effect.
Is there some specific settings that need to be used in this scenario?
