Resolving SecureClient “cannot connect to gateway” problems
After a lot of painful diagnosing I found that my Netgear Router has a setting for “NAT Filtering” that defaults to Secure…and when set to Open it resolves a frustrating problem with the Checkpoint SecureClient VPN software which was causing “Cannot connect to gateway” problems. I found lots of threads online but nothing clear (and Checkpoint’s software and error messages leave a lot to be desired). So if anyone’s struggling with their connections from this thing, try fiddling with your NAT filtering on your router. I’m still unclear from Netgear’s perspective of how “Open” increases my vulnerability though, so I’m hesitant to use it.
Currently using VPN-1 SecureClient NG R56 HFA1 Build 031.
Good luck.
