The Remote Subnet format must be IP address/netmask (e.g.

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 the L2TP client peer.
If you enter 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.
