[Openswan Users] IPSEC Failover?

[Stefan Drees]

Hi,
i need some tips for an ipsec "failover" solution.
I have two ISP connections, one main and one for failover.
If connection to the internet via ISP1 is lost, an HW router
switches automatically to ISP2.

ISP1
/ \
VPN1--RTR--< > INET-----VPN2
\ /
ISP2

I tried to copy the first connection on VPN2 only changing the 
ip-address (same ids).
I set uniqueids=yes and thougt the previous connection from VPN1 via 
ISP1 should be deleted,
if the connection from VPN1 via ISP2 is initited but it doesn´t.

Any hints how to solve these problem? Are there any other solutions for 
these?

Thanks, in advance.
