Advanced Step-by-Step Guide: Setting up Site to Site VPN on Check Point Firewalls!
Don't forget to add Local Encryption domains for GW1-192.168.1.200 (In my case local encryption domains are already setup so not specifically added)
Below are steps to add encryption domains :
Steps 1 - Go to Security Gateway General Properties and click Network Management.
Step 2: Select VPN Domain and Select User Defined.
Step 3: Add Network which is participating in VPN example in my case I have already have below networks added there :
Network 1: 192.168.1.0/24
Network 2: 10.10.10.0/24
Network 3: 172.16.0.0/24
Step 4 : Click OK and Install Policy
