Because 127.0.0.1 - 127.255.255.255 are reserved address for loopback purpose this mean any packet sent to any of those address is loopback. This is standard address IPv4 for loopback traffic.

Although, the SSL VPN client from Sangfor is extremely hard to use - Changing the default DNS server without any notification, hijacking all

The IP domain system includes loopback addresses, which allow devices to transmit and receive data packets.

IP address is a unique reserved IP address range that begins at 127.0.0.1

SSL VPN force to send 127.0.0.1 because it is the default behavior on a network.

A loopback address is a unique reserved IP address range that begins at 127.0.0.0 and ends at 127.255.255.255, albeit 127.255.255.255 is the broadcast address for 127.0.0.0/8.
The loopback addresses are embedded into the IP domain system, allowing devices to send and receive data packets.

A loopback address is a separate reserved IP address range beginning at 127.0.0.0 and ending at 127.255.255.255.
