Manual port forwarding, if the modem router
does not support UPnP
If the SIP ports of the modem router are not open by default and it does not support UPnP, the
appropriate WAN ports on the modem router Gateway must be forwarded manually by
accessing the modem router Gateway browser programming as per the example in the
Appendices.
UDP packets, typically on WAN ports 50000 to 50479 of the Gateway, should be forwarded to
the local IP address of the Opera system and also TCP packets on port 5075 and packets on
browser port 7000 on the Gateway should be forwarded to the Opera system port 80.
It may well be necessary to lower the level of Firewall protection, as described in Step 2 of the
example in the Appendices.
