GRE Tunnels
Figure 4-245. Example GRE Tunnel (Including Tunnel Interface)
8. For Tunnel IP Address, type the TMS zl Module’s IP address on the tunnel
interface (indicated by 5 in the figure).
This IP address is a virtual address, and it must not be part of an existing
TMS VLAN or other subnet in your network.
This address will be the source address for tunneled packets.
9. For Peer IP Address, type the same IP address that will be configured on
the tunnel interface on the remote tunnel gateway (indicated by 6 in the
figure).
This address will be the destination address for tunneled packets. It is a
virtual address.
10. For Firewall Zone Association, select a zone for the tunnel interface.
This zone will be the source zone for traffic that arrives on the tunnel and
the destination zone for traffic that is sent across the tunnel.
11. For Source IP Address, type an actual IP address on the TMS zl Module
(indicated by 1 in the figure).
Specify the IP address on the VLAN that the remote tunnel endpoint can
reach.
12. For Destination IP Address, type an accessible IP address on the remote
tunnel gateway (indicated by 3 in the figure and different from the address
configured on the subnet reserved for the tunnel).
