I Do control the checkpoint FW.

After investigation in WireShark I Saw the client also requested TCP 264 for
download Checkpoint Topology

After this - i've succeeded to create the site. but not able to fully
connect. I will try to solve this.

I Also found some couple of more specific ports I need to pat them for
secureremote / client
by looking in those sites.

One more question - Is there a way to do a nat/pat for Ip Protocol
numbers like esp IP Protocol = 50 for other protocols

ip nat inside source static esp 192.168.1.1 80.1.1.1

for example - IPSec AH =IP Protocol 51 ?
