Hi guys,

I have problem setting up port forwarding on new Orcon fibre modem, the netcomm wireless. My fibre got connected last week and I had to move all my network configuration from old black modem to the new one which has Gigabit LAN. I have few virtual servers hosted in my LAN and I need to access them at work. I am using no-ip dynamic DNS service and ddclient on my Linux box to report the public IP address to no-ip. When I configure all ports without enabling loopback, I can't see any of my server using no-ip URL even if I try to do them from my private LAN, but when I enable loopback LAN with forwarded ports, they work fine and I can access them from my private LAN, but still are not accessible from Internet. I am kinda sure there is something wrong with the modem set up and not with my virtual servers as they used to work before with old modem and still working when loopback is enabled.

I have read in one of the old threads which netcomm SPI firewall technology is causing issue, but looks like firewall is not enabled on my modem.

I have already contacted Orcon and they said, they only support basic Internet connection which does not make sense to me when you want to access your network. I do not use Internet only to access Facebook. Orcon customer service really sucks. Does anybody have any idea why it is happening and how I can fix my port forwarding issue? The modem model is netcomm wireless Nf4V. Many thanks.

Cheers,
Morteza
