Each entry must be specified in the "IP network address/subnet mask/gateway IP address" format. This Virtual DHCP Server can push the classless static routes (RFC 3442) with DHCP reply messages to VPN clients. Whether or not a VPN client can recognize the classless static routes (RFC 3442) depends on the target VPN client software. SoftEther VPN Client and OpenVPN Client are supporting the classless static routes. On L2TP/IPsec and MS-SSTP protocols, the compatibility depends on the implementation of the client software. You can realize the split tunneling if you clear the default gateway field on the Virtual DHCP Server options. On the client side, L2TP/IPsec and MS-SSTP clients need to be configured not to set up the default gateway for the split tunneling usage. You can also push the classless static routes (RFC 3442) by your existing external DHCP server. In that case, disable the Virtual DHCP Server function on SecureNAT, and you need not to set up the classless routes on this API. See the RFC 3442 to understand the classless routes.
