Operafone IP Executive Installation Guide

By default the Opera system implements port forwarding of UDP packets on ports 50000 to 50031 from
the Gateway to the local IP address of the Opera system. Similarly, for TCP packets on port 5075. It
also forwards port 7000 to port 80 on the Opera system to allow remote browser access. Note: For
security, remote access to the Opera system browser is restricted to only those public IP address listed
in the RAS IP addresses table.
5.3 If the modem router is not at the default Gateway IP address
If the default local IP address of the modem router has been altered from 192.168.1.254, the Opera
system must be manually programmed with the IP address of the Default Gateway (i.e. the router) for
Internet access. The local Default Gateway IP address is entered on the IP Settings browser page. This
allows the Opera system to direct outgoing traffic to the correct Internet gateway. The Gateway
Configuration page is updated automatically to display the Local IP Address entered (192.0.0.229 in the
screen example shown above).
5.4 If the modem router does not support Universal Plug and Play
If the SIP ports of the modem router are not open by default and it does not support UPnP, proceed to
manually program port forwarding at the modem router, as described in Section 4.4 of this manual, Port
Forwarding, and also lower the level of Firewall protection, as described in Step 2.
