The previous vpn clients, version 3.8.16 and 3.9.0 worked for 5-6 hours. After that, if trying a new connection it will display the same error

The issue seen due to the NAT device between vpn server and vpn client. With the new ike..nlm, a new fix was introduced that causes the 4 packet on IKE phase I negotiation coming from server to change the udp source port to 4500. This packet was being discarded by the NAT device, not reaching the vpn client and causing the failure.

There is a new ike.nlm with the fix for this issue. It is available in the  bm39sp2_ir1 patch and it is version 7.02.02, dated 12-nov-2009
