Phase1 failing between Cisco ASA Version 7.0(4) and Checkpoint Checkpoint NGX R65 Software Version 4.2 ?

Unanswered Question

Hi,

Cannot get VPN to come up at all between a Cisco ASA and Checkpoint. Below are the hardware/software configurations

Checkpoint NGX R65

Model IP560

Software release 4.2 – BUILD106a02

Software version releng 1515 11.18.2209-195037

Configured in a high availability pair

Hardware:   ASA5520, 512 MB RAM, CPU Pentium 4 Celeron 2000 MHz

Cisco Adaptive Security Appliance Software Version 7.0(4)

The Checkpoint Firewall rebooted a week ago (power interruption) and since then we cannot get the VPN to come up at all. This VPN was working fine before for a couple of years, but for whatever reason , it will not come up at all now since the power outage

The 3rd party who look after the Checkpoint have been cooperative and we have exchanged settings, but we cannot see why Phase1 is failing all the time. Never gets past Phase1

The settings on ASA are as follows

Hello,

In the configuration, I did not see the cryptomap being applied to any

interface. Can you please try applying it to the internet facing interface

and see if that helps?

crypto map CRYPTO_MAP_INTERNET interface

Hope this helps.

Regards,

NT
