VPN problem for FW-1 Checkpoint

Subject: VPN problem for FW-1 Checkpoint
Date: Tue, 19 Oct 2004 20:08:26 +0800
Hi all,

I have a problem with production firewall FW-1 Checkpoint with VPN running constantly for 2 years. However with a normal policy update yesterday, the VPN function stopped working. VPN is using IKE with DES, MD5, shared secret. Tunnel checked out fine on both site firewalls , all configuration is correct.

I have 2 types of errors, encryption failure: no response from peer.scheme: IKE

and

encryption failure: Packet is not IPSEC scheme: IKE

Any Checkpoint gurus out there can shed light on this problem or share experiences and troubleshooting on this form of failure?

Regards,
Alvin
