GRE Tunnel configuration between two GWR-HS Routers
GRE tunnel is a type of a VPN tunnel, but it is not a secure tunneling method. Simple network with two
GWR-HS Routers is illustrated on the diagram below (
Figure 60
). Idea is to create GRE tunnel for LAN to LAN (site to
site) connectivity.
Figure 60 – GRE tunnel between two GWR-HS Routers
The GWR-HS Routers requirements:
•
Static IP WAN address for tunnel source and tunnel destination address;
•
Source tunnel address should have static WAN IP address;
•
Destination tunnel address should have static WAN IP address;
GSM/UMTS APN Type: For GSM/UMTS networks GWR-HS Router connections may require a Custom APN. A
Custom APN allows for various IP addressing options, particularly static IP addresses, which are needed for most
VPN connections. A custom APN should also support mobile terminated data that may be required in most site–to–
site VPNs.
The GWR-HS Router 1 configuration:
•
Click Network Tab, to open the LAN NETWORK screen. Use this screen to configure LAN TCP/IP settings.
Configure IP address and Netmask.
•
IP Address: 192.168.4.1,
•
Subnet Mask: 255.255.255.0,
•
Press Save to accept the changes.

•
Use SIM card with a static IP address, obtained from Mobile Operator. (Note the default gateway may show,
or change to, an address such as 10.0.0.1; this is normal as it is the GSM/UMTS provider’s network default
gateway).
