Multiple IPSec tunnels between two ISRs

Hello, I have a 2851 at HQ and 2821 at 2nd site. Using IPSec VPN to connect the two LANs and it is working fine. Now I want to connect another LAN at each site across the same VPN. I want to keep traffic separate between the LANs. Is this possible?

Re: Multiple IPSec tunnels between two ISRs

you can't use other crypto map if you have to use the same ip for te peers.

If you have others ip's in each end to terminate the tunnel you can use other crypto map.

If the answer is no, then you can manipulate te acl of interest traffic to decide wich lan can reach to witch lan .

You only have to make your access-list to permit only the networks sources and destiny that you have to be access.

Don't forget qualify me.

Arturo,

Do I use the same crypto map and just change ACL to specify new LANs or do I need to make an another crypto map?

Thanks, Mitchell
