CONFIGURATION

The tunnels are active after selecting Create x GRE tunnel. In the singles window it

is possible to define the IP address of the remote side of the tunnel (Remote External IP

Address), internal IP address of the local side of the tunnel (Local Internal IP Address),

internal IP address of the remote side of the tunnel (Remote Internal IP Address), address

of the network behind the remote side of the tunnel (Remote Subnet) and the mask

of the network behind the remote side of the tunnel (Remote Subnet Mask). The GRE tunnel

is used for connection of two networks to one that appears as one homogenous. Last item

be on both sides of same, differently router drops packets.
