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

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 endtoend connectivity from your PCs to the

remote side of the CIP connection and beyond you must add

routes having the STPro Ethernet interface IP address as gateway.

By specifying 0.0.0.0/0 as destination and the STPro local

Ethernet IP address as gateway the STPro 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

STPro as gateway.

Configuring routes for the STPro is described in section 14.5.
