Introduction to SCVPN Address Pool

The SCVPN servers allocate the IPs in the SCVPN address pools to the clients. After the client connects to the server successfully, the server will fetch an IP address along with other related parameters (e.g., DNS server address, and WIN server address) from the SCVPN address pool and then allocate the IP and parameters to the client.

You can create IP binding rule to meet the fixed IP requirement. IP binding rule includes IP-user binding rule and IP-role binding rule. The IP-user binding rule binds the client to a fixed IP in the configured address pool. When the client connects to the server successfully, the server will allocate the binding IP to the client. The IP-role binding rule binds the role to an IP range in the configured address pool. When the client connects to the server successfully, the server will select an IP from the IP range and allocate the IP to the client.

After the client successfully connects to the server, the server will check the binding rules in a certain order to determine which IP to allocate. The order is shown as below:

1. Check whether the IP-user binding rule is configured for the client. If yes, allocate the bound IP to the client, but if the IP is occupied by aother client, the server will refuse the client's login request; if no, go on checking.
2. Check whether the IP-role binding rule is configured for the client. If yes, get an IP from the IP range and allocate to the client. If no, the server will refuse the client's login request.

Note: IP addresses in the IP-user binding rule and the IP address in the IP-role binding rules should not overlap.
