Remote Subnet
A Must filled setting
Specify the remote subnet for this L2TP tunnel to reach L2TP server.
The Remote Subnet format must be IP address/netmask (e.g. 10.0.0.2/24).
It is for the Intranet of L2TP VPN server. So, at L2TP client peer, the packets
whose destination is in the dedicated subnet will be transferred via the L2TP
VPN tunnel. Others will be transferred based on current routing policy of the
security gateway at L2TP client peer.
If you entered 0.0.0.0/0 in the Remote Subnet field, it will be treated as a
default gateway setting for the L2TP client peer, all packets, including the
Internet accessing of L2TP Client peer, will go through the established L2TP
VPN tunnel. That means the remote L2TP VPN server controls the flow of any
packets from the L2TP client peer. Certainly, those packets come through the
L2TP VPN tunnel.
