No traffic flow through L2TP VPN tunnel
Please follow the instructions below if you have successfully established
an L2TP VPN connection but cannot pass traffic through the tunnel.
By default L2TP clients are programmed to send all traffic through
the L2TP connection once established. If you have disabled this
option you will need to manually create routes on your devices
operating system to route traffic through the tunnel accordingly.
Make sure there are no IP conflicts. The ZyWALL’s internal (LAN)
IP scheme and the L2TP IP pool should be on different subnets,
using the same IP scheme can cause routing issues.
Create a policy route on the ZyWALL to specify that any traffic
destined for the L2TP IP Pool needs to take a hop (Next-Hop) at
the L2TP VPN tunnel.
