I am trying to connect an azure private network to a on premises network using an Azure site-to-site VPN tunnel and a Check Point Security Gateway running GAIA R77.20.
The VPN connects correctly but all packets are dropped by the firewall with an error "Encryption failure. According to the policy the packet should not have been decrypted". Does anyone have any suggestions why this is happening?
The configuration of the firewall is as per the microsoft suggections.
