Normally L2TP server has route for 192.168.1.1/24 or 192.168.0.1/24. Please check the L2TP
server has the route of 192.168.8.0/24 if your H820 router is with IP 192.168.8.1.
For example, if H820 LAN IP is 192.168.8.1 and assigned L2TP IP is 172.1.1.2. Then at the L2TP
server, need add a route for 192.168.8.0/24 and gateway as 172.168.1.2. Meanwhile, we suggest
L2TP Server use fixed L2TP IP rule for L2TP client, otherwise need modify the route’s gateway
every time because the L2TP client gets a random L2TP IP.
Typical Application (1) E-Lins Router as L2TP Client --- Connects --- E-Lins Router as L2TP
Server:
Once L2TP setup, the two E-Lins router will add the route themselves automatically.
Typical Application (2) E-Lins Router as L2TP Client --- Connects --- Other Router/Windows as
L2TP Server:
Once L2TP setup, the E-Lins router will add the route itself automatically. But the L2TP Server will
not add the route automatically. So need manually add it.
Typical Application (3) Mobile Phone/Portable Devices as L2TP Client --- Connects --- E-Lins
Router/Windows/Other Router as L2TP Server:
No need add the route.
