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 (W)LAN, e.g. 10.0.1.x, and privilege
access to the LIS - and its beyond (W)LAN - to this subnet by
adding a route pointing to the remote access router (implicit, or
explicit) but with now 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 AST570 Ethernet interface IP address as
gateway.
By specifying 0.0.0.0/0 as destination and the
AST570 local
Ethernet IP address as gateway the AST570 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
AST570 as gateway.
Configuring routes for the AST570 is described in section 14.5.
