SA negociation between VPN-1 AI-R55 and Cisco VPN Concentrator 3030

[blaxxis]

Hi,

I have a "problem" with a site to site connection. The IPSEC tunnel is dropped down every 6 mns and half (about) and become UP just after. It seems to be transparent for the customer (he received the feed correctly) but I believe that it is not good.
I have another site to site tunnel with another customer in AI-R55 and the tunnel can stay connected several days without any cut. Is there any parameter that my customer should check on it NOKIA checkpoint?
Thank you,

Uncheck PFS on the checkpoint side first.
There was few Cisco PIX/IOS to Checkpoint discusions here. Cearch on keywords cisco. There was configuration doc links included.

Also here it two Cisco 3000 to CheckPoint samples http://www.cisco.com/en/US/products/...ples_list.html
