I have a Checkpoint setup, R71.30 and I am preparing a new setup which is R75.40. I am trying to create a externally managed gateway for the IPSec VPN on R75.40. I am setting the same properties of R71.30 version. But on newer version I am getting the following warning. Why is this error occuring only on the R75.40, and under link selection what should be my selection? I have selected the "Always USe this IP Address->Main Address"

You have chosen the "main IP" method of IP selection for VPN Link Selection. However, this gateway's main IP is not a member of Topology table. Under this configuration Link select will not be functional.
