How to add AWS Load balancer host in Pritunl route

I’m using a self-hosted Pritunl server.

As of now, the only route configured is which allows all internet traffic to go through the VPN.

I want to allow only production server traffic through Pritunl which is using AWS Load Balancer, which only gives DNS, not IP address

Same as ALB, I also want to allow traffic to the production database on AWS RDS, which also provides only a DNS address same as ALB.

How can I configure the route in these scenarios?

Domains can’t be added to the routes. The route would need to be removed and the IP address for the domain can be added.
