Remote Access not connecting after first time.

Hi Everyone

I deployed the checkpoint Cloudgaurd firewall on GCP (Both Management server and Gateway). Configured the Remote access VPN (Split tunnel) and connecting with local user (For testing). Its connected on first time after connecting machine disconnects with internet. When trying to connect by second time, takes more time on "retrieving site information" Later it getting "Connection failed - site is not responding" error.

Anyone facing this type of issue, help me to sort out it.

MGMT = R81.20 Take 96

Gateway = R81.20 Take 96

Thanks

How are you adding the site to the client, by IP or DNS name?
In either case, the gateway’s Main IP (general tab of gateway object) is the IP that will be stored OR, if you’re configured Link Selection (either via the screen @AkosBakos showed or the Remote Access specific version here: https://support.checkpoint.com/results/sk/sk32229 ), that IP will be used.
If the Main IP is a private IP (or not reachable from the Internet) and you have not configured Link Selection correctly, what you are seeing is expected behavior.

You can also force DNS resolution on every connection using the following procedure: https://support.checkpoint.com/results/sk/sk103440

Yes, I focused only to the tipical issue only. There are a plenty other scenarios that can cause issues.

I using "selected address from the topology table" and chosed the external interface, Its private IP address only since gateway deployed on the Google cloud.

If i chose Statically NATed IP and entered the gateways public IP address, still the same issue.

On client side we used the IP address for a site configuration. I will try the article and update you.

Thanks for the assist.
