Most of the time it is not required (as well as for NetBIOS-Proxy), that the local network structure is propagated over RIP to the DMZ. Furthermore it is sometimes required, to propagate the known routes to a certain network, but not to learn routes from the network (eg. in the WAN). Therefore the RIP functionality can be set up for every network separately.
LANconfig: IP-Router / General / RIP networks
WEBconfig: LCOS-menu tree / Setup / IP-Router / RIP / LAN-table
