1.5 How do I deal with slow links across different sites?

Use traffic rules to restrict the traffic.

By default, the VPN traffic rule encrypts all the packets going out for the client and sends them to the VPN server. This adds unnecessary load to the tunnel.

Deployment

Do the following to deploy:

  1. Configure the client-to-site and site-to-site services.

  2. In the client-to-site policy, add traffic rules to encrypt traffic only for particular protocol or network.

  3. Add site-to-site protected network traffic rules with only protected networks as the destination.

IMPORTANT:If the traffic rules are not added, all the traffic passes through the VPN tunnel.
