I am trying to  implement IPSEC vpn between checkpoint ( running on nokia
650 4.1 sp2) and Cisco pix using IKE.
( using DES, SHA1, ESP+AH , Withot PFS) 
I have followed the chckpoint docs. WE got the tunnel working. IT works only
if any traffic is 
initiated from pix side. then  i can also telnet to their routers ( i.e.
network behind pix). After some time if there is not traffic from their side
tunnel dies. If i initiate traffic from checkpoint site( i.e. network behind
checkpoint) the  tunnel doesn't come up. I get an error in the checkpoint
log viewer . IKE log: received notification from peer: no proposal chosen
Negotiation id:343434f3434.

Can somebody help me. What should i be checking
