To further complicate the situation, the individual servers also run firewalls which only allow access from specific IP ranges 1. Please identify what changes (if any) need to be made on our VPN appliance to restore connectivity to the client's servers. 2. After verifying that the VPN configuration is correct, what would you do to confirm that we have access to the servers? Please indicate what specific commands you would run.  3. Assuming that we still do not have connectivity to the servers, what request would you make to the client to check that we have been given access to their network? What information would you request from them?
