VPN servers allocate IP address ranges to VPN clients and mediate DNS queries of VPN clients. Any of these can be affected by a change to the VPN server’s IP address or domain name. Additionally, the VPN server contains routing definitions based on IP addresses. A change to the IP address can make those routing addresses unreachable.
Check all the VPN settings when changing the IP address of the VPN server.

If you change the web server’s IP addresses, use Server Admin to change any virtual hosts that use a specific IP address. The default
For either change, if you configured Mobile Access for web (or possibly other proxy settings), delete and recreate the proxy settings for all affected hosts.
