Anyone know if one can configure the Netcomm NF4V as used by Orcon to port-forward to other subnets than the default LAN subnet?

Got meself a brand new Orcon connection and went to configure port-forwarding on the NF4V as the connection goes live tomorrow.

Hmm. Can not port-forward (virtual servers the nF4v calls 'em) to a subnet that is different to the modem lan subnet, despite adding previously in a static route in the NF4V for that internal range. Modem just states there was an error adding the entry.

Despite most of our calls being to the handheld head warmers, the real power in the household has decreed we need a real phone line so I can't ditch the NF4V.

Port forwarding is also rather useful for me and my internal network has a few VLANs in order to keep the fandamnily away from my work gear, etc.

I'd REALLY prefer not to have to collapse internal vlans and the associated ip readdressing.

It MAY be that because the wan connection is not yet live that port-forwarding can not be configured. (Hoping this is the case but if not I'll be internet-less tomorrow and the afore-mentioned fandamnily will start to get ornery and I really don't want that)!

Anyone done this before or have any ideas?

Keep your network in it's current form, setup the Orcon supplied router on a different subnet, DMZ your primary router in the Orcon config/forward all ports, and setup a DHCP WAN on your current router.

Alternatively, use your current router as your primary router in place of Orcon's router, and then setup an interface for the Orcon router, which you'll need to change to be a DHCP client with a static IP. Those are two solutions I've used to work around issues like you've described, YMMV.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

Bleh.

Can't replace router otherwise I lose the phone line.

I have set my router as the DMZ but I have a bigger problem.

Pings from inside get stopped at the NF4V. Pings from my router reach the NF4V so local subnet pings work to the NF4V

Pings from the NF4V reach my router but not beyond. Again, local subnet pings work.

Placing a PC on the same network as the NF4V LAN (my router's WAN) can ping everywhere internally so it's not the internal network routing.

Pings from my internal network can reach the PC on the NF4V's LAN. Again, not the internal network's fault.

It's really looking like this thing can't interact with anything outside it's defined LAN subnet.

What a pain in the posterior!

TBH I am amazed when any router for the consumer market even has any mention of more than one internal network.

Can you not just put the WAN of their router onto the lan of a real router to get voice service? Or just forget about it since mobiles have more than enough calling time on them now.
