We use basic global protect functionality (no global protect licenses) to connect with SSL VPN. One of user (businnes owner) must have always the same IP address when he connect via SSL VPN. How can I resolve this? In global protect configuration isn't possible to reserve IP addresses for MAC address (like in DHCP server).
MAC addres reservations for DHCP work because the firewall gets teh DHCP request and can evaluate the MAC address. For such a feature to work for VPN users, the VPN client would have to sent it's MAC address as part of the authentication process. From the firewall's point of view, every VPN connection comes from the router's MAC address since they all come from outside.
I'm not aware of such a capability but perhaps someone else has a solution for this.
A form of this functionality can be obtained by configuring a user specific client configuration on your portal that points to a second external gateway. The second gateway would be configured to only distribute one IP address.
This capability exists for the more common use case of defining specific user groups that might get different configurations and networks settings, so it doesn't really scale to doing this for dozens of individual IPs, but for a one-off it should work fine.
When I try to configure "Cliente Configuration" into Globalprotect Gateway with only one IP address, I obtain this message: "SSLVPN: Invalid IP pool value: X.X.X.X. Subnet is smaller than minimum allowed value 30." Is it not possible to configure only one IP in a pool? What is the reason for it?
Thank you very much.
This is an expected error, the minimum subnet to create a gateway pool is /30. What you can try is to configure a pool in a different gateway just for that specific user. He will get the same IP address i.e. the 1st IP address from that pool every time he disconnects and connect back as there would be no other users who would be using that defined pool. This is just a workaround, what I would also suggest if you can do a feature request so that a user can be assigned a specific IP address based on HIP match, etc.
