Hello, I am facing some troubles with a site-to-site VPN between a CheckPoint Ngx and a Sophos UTM firewall.
The vpn uses ike to encrypt the traffic but sometimes it happens that the link is dropped down and it's not bringed back automatically once again.
Seems like both devices are configured as initiator while one of them should be configured in "responder only" mode. I would like to change this settings on the Checkpoint side since the traffic will usually be initiated from Sophos (and so, it needs to be able to initiate the link).
How can I check and/or change this settings inside the Checkpoint appliance?
Thank you.
