Has anyone had more than 1 subnet working across an IPSEC VPN tunnel between Vigor 2600 and Cisco IOS

I have tried 2 separate VPN tunnels between same public IP but ony 1 will come up at a time

I have added another local lan subnet to the vigor under "More" in the subnet setting field

The main subnet works fine and stays up solid.

Vigor 2600

Cisco 2601

172.16.80.0/24

172.16.2.0/24
172.16.80.0/24

172.16.18.0/24

My Netgear DG834 did this fine but it died recently

I need the second subnet as its for voip from my office voip subnet to home



When I ping 172.16.18.1 from PC 172.16.80.1 I see the cisco send a reply to the Vigor but it fails to reach my PC on the 172.16.80.0 subnet

I have the latest Vigor f/w

Any suggestions ?

I found this hunting around here for a solution to a simnilar issue with a 2820Vn. The "More" button only works talking to another Draytek - basically, the only remote subnet that counts otherwise is the one defined in section "4. TCP/IP Network Settings". HOWEVER! You can add additional tunnels - all the same settings bar the destination network which you can change to be your other subnets; I'd also make sure that the ping to keep alive box is adjusted to an address consistent with each subnet. I now have a 2820Vn talking to a Sonicwall PRO4060 on three subnets with this method.
