IP Line Description, Installation and Maintenance
Note 1: If firewall security is properly configured in the customer's
Management GW router, and if the Modem Router is allowed access over
the customer’s enterprise network to other IP Telephony nodes on remote
ELAN subnets, define a default network route pointing to the
Management GW IP address on the local ELAN subnet. Alternatively,
define up to four different static network routes or host routes in the
Modem Router to limit routing access from the Modem Router to the
customer’s enterprise network.
Note 2: To prevent access from the Modem Router to the TLAN subnet
through the Management GW router on the ELAN subnet, disable RIP by
setting RIP Direction = None, and remove all static routes or disable a
particular static route by setting Active = No.
15 Enter menu selection number 1 to edit the first static route.
Menu 12.1 - Edit IP Static Route is displayed.
