GRE Tunnel configuration between two PRESTO Advanced Routers
PRESTO Advanced tunnel is a type of a VPN tunnel, but it isn't a secure tunneling method. Simple
network with two PRESTO Advanced Routers is illustrated on the diagram below (
Figure 38
). Idea is to
create GRE tunnel for LAN to LAN (site to site) connectivity.
Figure 38 - GRE tunnel between two PRESTO Advanced Routers
The PRESTO Advanced 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 PRESTO Advanced 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.
