Task Remarks
Configuring a route for packet
forwarding through the tunnel
Required
Each end of the tunnel must have a route (static or dynamic) for packet
forwarding through the tunnel to the other end, so that GRE
encapsulated packets can be forwarded normally.
When configuring a route through the tunnel, you can configure a
static route, using the address of the network segment that the original
packet is destined for as its destination address and the address of the
peer tunnel interface as its next hop. Or, you can enable a dynamic
routing protocol on both the tunnel interface and the interface
connecting the private network, so that the dynamic routing protocol
can establish a routing entry that instructs the firewall to forward
packets through the tunnel.
For information about static and dynamic route configuration, see
Network Management Configuration Guide.
IMPORTANT:
It is not allowed to set up a static route whose destination address is in
the subnet of the tunnel interface.
