Hello.

I have 2 sites. Site A is connected to the internet via an E1 and Site B which is also connected to the internet via an E1.
I am currently running an IPSEC vpn tunnel between a PIX 515E at site A and a Cisco 2610 at site B.

I have been having problems with the E1 provided to site B and want to be able to create a backup VPN over DSL should I have further issues.

I have a WIC card within the 2610 at site B. This is connected to DSL and has a Fixed IP address.
The failover will need to be from the PIX at site A to the DSL connection at site B.

I seem to be having problems setting this up so any help would be very much appreciated!

Thanks guys,

If you just setup the PIX to look like there are two different peers for the same traffic, it will use the one with the lowest priority number and the next one if necessary:

Something like this:

rypto map outside_map 10 match address outside_1_cryptomap
crypto map outside_map 10 set peer <T1 ip address>
crypto map outside_map 10 set transform-set ESP-3DES-MD5
rypto map outside_map 20 match address outside_1_cryptomap
crypto map outside_map 20 set peer <DSL ip address>
crypto map outside_map 20 set transform-set ESP-3DES-MD5
