The possibility exists to add routes yourself, e.g. to be more
specific in the source IP address pool.
The default added routes have
any
as source address, meaning
that all local hosts can use this gateway to connect to the LIS via
the CIP interface.
However, you might want to embed restrictions in LIS access by
creating a subnet in your LAN, e.g. 10.0.1.x, and privilege access
to the LIS - and its beyond LAN - to this subnet by adding a
route pointing to the remote access router (implicit, or explicit) but
now with source IP address pool 10.0.1.0/24.
Of course then the default IP routes configured by default, must be
deleted.
In order to have endtoend connectivity from your PCs to the
remote side of the CIP connection and beyond you must add
routes having the AST710 Ethernet interface IP address as
gateway.
By specifying 0.0.0.0/0 as destination and the
AST710 local
Ethernet IP address as gateway the AST710 is configured as the
default gateway for all connection requests.
However, you can specify a destination IP address pool, e.g. if the
remote LAN's IP subnetwork is 192.6.11.x, you can add routes in
your PC's routing table with destination 192.6.11.0/32, and the
AST710 as gateway.
Configuring routes for the AST710 is described in subsection
13.5.2.
