D-Link DSL-2640R Port Forwarding [ Edited ]

[rtozer]

I am attempting to set up port forwarding for FTP ports on my D-link 2640R router supplied by Virgin.

I have set up port forwarding before on other routers with no hassle, but cannot get it to work on this one.

A quick search of the internet shows other people having the same issue, and the consensus appears to be that the shipping version of the firmware (1.06) doesn't work.

I downloaded the latest fw from d-link (1.11), but the firmware upgrade option on the router fails every time.

I'm forwarding to a NAS device, so there is no firewall on the device to interfere, and ftp does work internally on the LAN.

I'm using dynDns to handle the DNS lookup, and this is working correctly.

The NAS device has a static IP address assigned.

I've tried putting the NAS in the DMZ, and all combinations of on/off for uPnP, firewall etc.

I see the device itself claims to support ftp access via LAN and WAN for remote management, I have tried turning this off in case it is interfering.

I've used port checking sites seemyport canyouseeme etc to check the forwarding, and they always report that the port is not open/visible.

Basically, I'm out of ideas.

Has anyone encountered this problem on the 2640r?

Anyone know how to make the fw upgrade work?

Any further suggestions?

Thanks

Hi rtozer,

By updating the firmware and removing the Virgin Media software the router will be out of warranty. We only support the basic set up for wireless (name of network, security key, channel numbers) and to gain a connection on the ADSL network (username/password, type of connection, VCI, VPI, encapsulation) We do not support any advanced function within the router. sorry

My suggestion is to check out the Dlink support pages via the manufacturer website. Please go to the link below Dlink model 2640r, for FAQ and PDF file on how set up port forwarding.

Thank you for the response Amer_Z

"By updating the firmware and removing the Virgin Media software the router will be out of warranty."

Are you saying that the firmware version supplied is Virgin specific? 

If not, why would updating the product to the latest version void the warranty? 

"We do not support any advanced function within the router. sorry"

Does this mean that the functionality should be there but Virgin doesn't offer customer support, or that the hardware supplied (with virgin specific firmware installed?) does not support any advance functions?

I have already visited the site you suggested and have the read the FAQs and the section on port forwarding. Incidentally the instructions for port forwarding are for a different router (or at least a different version of the firmware). And clearly don't work. Nothing else was suggested there that I haven't already tried.

I am reasonably IT competant and have never had trouble with something as simple as port forwarding in the past. I am convinced that this version of the router will not do what I require.

Can Virgin supply a better router (assuming I leave the firmware unchanged)?

Regards

Richard

HI rtozer,

The firmware version supplied is specific to Virgin Media. The advanced functions are there to be used however not supported by us. The Dlink support page allowed me to choose the modem.

We only supply the Dlink router model 2640r. The link I posted was for this particular model 2640r. The link I gave you may have reset it to the main pages on the Dlink website. Go direct to the website and choose the model from the drop down list. There is a PDF file available.

Thanks

Your link did work correctly,  (and I found it manually last time anyway). The site's instructions for that router definitely don't match the web interface. I've found other guides which do match, and following these doesn't work either.

Thanks for the info though

Any other users managed to get port forwarding working on a 2640r?

Never mind, I got it...

I tried forwarding to a desktop PC using nc -l to listen on different port and that worked. So what I'd done with the router was correct...

I removed and reconfigured the NAS and now it works too. I suspect it was something to do with the static IP allocation, it lists a different Mac address now.  Odd that it worked internally before, or at all really...

Hi rtozer,

Glad you got it working Richard after a lot of perseverance.

Thanks

The 1.06 firmware is merely the standard shipping firmware for the DSL-2640R router prior to August 2010. As far as I'm aware there arent any customizations in the routers supplied by VM. I believe it's only a version of the router that another ISP provides that uses a custom firmware version.

Any more basic steps I can follow for this on the DSL-2640R? As I've put in my other post I am having port forwarding issues specifically with Dead Space 2, but there are other occasions where forwarding ports would be useful too.

Treat it as a hand holding exercise in port forwarding on a DSL-2640R for a noob 

A friend has pointed me in the direction of DyDNS to solve the changing IP, this the right direction?
