Hi, I have a Hub-Spoke configuration of VPN Tunnels from Remote Branches connecting to the central site. The tunnels terminate on PIX firewalls with version 6.3 software. This setup works fine.
Now, we have a new DR site which has a PIX 525 with version 7 software. I would like to create VPN Tunnels between the remote sites and the DR site.
Does anybody have sample configs with this scenario?
Thanks in advance.

Attached is a sketch of the setup I have. In this diagram, the remote branch is connected to the main branch on a vpn tunnel. This works fine.
The second tunnel to the DR site is configured but does not work. Is it possible to have Version 6.3 software on one end and version 7.x at the other end?

What are you trying to achieve here? Are you
trying to do a automatically failover if the
VPN tunnel between the remote branch and the
Main FW goes down and the vpn tunnel between
remote branch and DR FW will goes active?
If that's the case, it can NOT be done with
Cisco Pix. Pix is a piece of junk. You would
need Cisco IOS routers for that. With IOS
routers, it can be easily done.
By the way, do you work for AMEX? do you know
Alban Dani?

HI Kev,
What I'm trying to do is to have two tunnels from the branches. One to the main site and one to the DR site. If the branch lose connection to the main site for whatever reason, they should be able to re-route the applications to the DR Servers.
Sorry, I do not know Alban.

It took me a couple of weeks to figure this out, but it was a simple case of deprecated command.
I simply removed this line from the remote branch firewall configuration:
crypto map vpn 15 set pfs group2
The Version 7.2 software on the DR Site firewall does not need this parameter and the Phase 2 negotiation will fail if this parameter is kept.
