When you set up the VPN server, you must set up a DHCP server to designate addresses to clients, or you can develop a bank of IP addresses to designate to clients straight from the VPN server.

If this option is picked and the effective remote access policy is set to permit remote gain access to, the user will have the ability to attach to the VPN.

If this check box is made it possible for, VPN users will be able to access the rest of the network, assuming network firewalls and security-as-a-service settings allow. If the checkbox is not selected, these users will have the ability to access just the VPN server, however absolutely nothing beyond.

A firewall program or security as a service solution might likewise be to blame, so do not forget to evaluate those options' settings, if such components are present between the VPN server and the resources the user looks for to reach.

The very first possibility is that one or more of the routers included is performing IP packet filtering. I recommend inspecting the client, the server and any machines in between for IP package filters.
