GRE
Click the GRE tab on the Security page to add and delete GRE (Generic Route Encapsulation) tunnels.
The current tunnels are listed at the bottom of the page. Up to two networks that lie beyond the tunnel may be
specified, and routes to those networks are automatically created when the tunnel is established. Static local and
remote IP addresses are necessary to allow for tunnel automatic (re)connection.
Figure 28 Security–GRE
GRE Tunnel Configuration
Local IP Address
The local (typically WAN interface) IP address associated with the tunnel.
Remote IP Address
The remote IP address associated with the tunnel.
Tunnel IP Address
The IP address assigned to the tunnel interface. For example, 192.168.10.100.
Tunnel Subnet &
Mask
The tunnel subnet and mask that must include the above Tunnel IP Address. For
example, 192.168.10.0/24.
Remote User Subnet
1 & Mask
The IP network representing that of the remote user subnet, accessible via the
tunnel. For example, 192.168.20.0/24.
Remote User Subnet
2 & Mask
A possible second IP network representing another remote user subnet. For example,
192.168.15.0/24.
NOTE All subnets must be different from one another. If more than two
remote user subnets are necessary, additional routes can be setup manually
via the Router | Static Routes web page using the Tunnel IP Address as the
gateway.
3.7 Serial
Click Serial on the main navigation pane to access the serial port configuration page.
External Serial
Click the External Serial tab on the Serial page to configure the RS-232 Serial Port parameters and Packet
Assembler and Disassembler (PAD) functionality. The PAD feature forwards requests that come in on a specific port
to the Serial connector.
