How to route traffic between 2 Seperate VPN's (ASA 8.2)

Hi there I have 2 separate VPN tunnels from my ASA at present up and running. One VPN to a 3rd party and the other to cloud Service.  I want to be able to allow the 3rd part VPN trafffic to also be able to get to Cloud network over that other VPN tunnel and same with the Cloud traffic should be able to get back to the 3rd Party network.

 

CloudVPN<---->ASA<------->3dPartyVPN

Traffic should be able to flow from cloud through my ASA over to the 3rd PartyVPN

 

Do i need to create a static route on the ASA and or Ammend ACL + NAT mappings or add each others subnets to the opposite VPN tunnels.  Config is below for the ACL and NAT. Im new to ASA config and this is v 8.2 which is making is trickier. I no there is 2 object groups with same details but I was just trying to keep everything separate.

 

If you need anymore let me know.....

Hi,

This will be helpful :https://supportforums.cisco.com/document/12015091/cisco-asa-vpn-spoke-spoke-communication-hub

For nat you can use

nat (outside) 0  access-list <list for traffic between two spokes>

HTH

Abaji.

 

 

 

Perform the NAT 0 on the outside interface then and not on the inside? Or both?

I hope you reviewed the link, nat exempt on outside is for traffic between two spokes and nat exempt on inside is traffic from ASA to the respective spokes

 

HTH

Abaji.
