Can IOS router lifetime larger than 86400 ?

Hi,

Is there any way we can keep L2L VPN connection for few days?

I have a customer has one HQ office and few remote telworker. Every time when telworker want to talk to each other, they have to ping each other to get VPN tunnel up, but the tunnel only last for one day. The lifetime on IOS router only can be setup as 86400 seconds.

How can I make vpn tunnel last longer ?

The customer use Cisco Call Manager,ASA and router.

Thanks,

Sen

The HQ office is in Dublin Ireland, but Teleworker is around in Boston USA.

Thanks,

Yeah, but the lifetime on IOS router is 86400 as max.

Is there any way I can setup the value larger than 86400 ?
