As with a site-to-site VPN, SecuRemote requires both binaries that support it and the licenses to enable it. The basic SecuRemote functionality is provided as part of a standard encryption license, although you must specifically request the functionality when requesting your license. The SecureClient functionality comes at an additional charge beyond an encryption license.
If you have CPVP-VSR as part of your license string, you have SecuRemote functionality. If you have CPVP-VSC as part of your license string, you have SecureClient functionality. The number that appears after either of these designations is the number of users your license permits.
