Port forwarding to different LAN servers listening in the same port

Hello.

I have several devices in my home LAN (2 PCs, NAS, ...) that implement web servers listening in port 80 (cannot change port number).

When I want to access them from the office, I configure port forwarding, but I can only acces one of them, because the external port and the internal port has to be the same.

I also have an old Linksys router when you can use different external and internal ports for forwarding (i.e. myaddress.com:8081 ---> PC1:80 and myaddress.com:8082 ---> NAS:80).

How can I do the same with a Netgear DGND3700 and be able to access all of my devices at port 80?

Regards.

Re: Port forwarding to different LAN servers listening in the same port

Hi, I dont think this is possible with the DGND3700 but should be possible using different incoming port numbers to a port translation server on one of the PC's... http://www.boutell.com/rinetd/ HTH

Re: Port forwarding to different LAN servers listening in the same port

most home end router will not do port translation

what you see is what you get so you should see that there is not want to redirect so you can not do with this model from the interface. Not sure you can do that with telnet. go to myopenrouter.com and find telentenabler,ext then play with the command if you can redirect the port

Thanks, although this solution requires one pc to be always on.

Re: Port forwarding to different LAN servers listening in the same port

Hi There - appreciate this post is a year old but I'm seeing the same issue. I have had Belkin routers in the past where it's easy to direct ports.

I have 4 wireless IP cameras and a DYNDNS - with Belkin it was easy to direct XXXXXX.dyndns.org:501 to my internal camera at 192.168.2.201

Simples!

I cannot see how to do this with this model - the only way around it is to set the IP cameras Port to match so to access I need to enter 192.168.2.201:501

it looks like other Netgears have this ability;
http://portforward.com/english/routers/port_forwarding/Netgear/DGN3500/Panasonic_BL-C131.htm

It seems such a basic function to be missing on this top end (Domestic) router.

I am running the latest firmware (.17)

any help really appreciated - thanks

Re: Port forwarding to different LAN servers listening in the same port

Thanks for the reply but it does seem a very backwards step.

Following this route means I have to fundamentally change the port on 4 pieces of equipment for the sake of a router change. This seems to be a very basic request available on other domestic routers - I know as I've had many over the years and this has never been a problem. Belkin have it as standard and even BT Home Hubs have it as standard!

All I want is for the router to listen out for a request on port 501 and forward it to port 80....for more than one device.

I know other Netgear routers have this - look at this link

http://kb.netgear.com/app/answers/detail/a_id/20917/~/how-is-port-forwarding-configured%3F#GenieAnch...

On the second screenshot down - it clearly has a check box (greyed out) asking "use the same port range for internal port" this is where you would put in port 80 for each rule I was setting.

I hope this may change with future firmware updates as the router's great.

Thanks in advance for any help or if the Netgear Admins are looking in - I have tried 2 times now to ask this question with your live help. Each time I ask the question, it's obvious that the 'script folllowers' in your support center don't know the answer and BANG......my conversation window hangs.......ie: they cut me off to try and answer a question they can resolve!

Thanks in advance for any help here - it really is frustrating

ps...I have attached a screenshot from my Belkin router showing exactly what I want to do Smiley Happy

Unfortunately if you have an option to specify then it doesn't have an option regardless other model or manufacture did. Smiley Happy

Thanks - I will try Netgear again - it seems such a fundamentally basic feature missing from their top routers.....this time I might be lucky that they won't cut me off!

To re-cap all I want to do is forward to 4 different webcams

XXXXX.dyndns.org:501 -->>-- 192.168.2.201:80
XXXXX.dyndns.org:502 -->>-- 192.168.2.202:80
XXXXX.dyndns.org:503 -->>-- 192.168.2.203:80
XXXXX.dyndns.org:504 -->>-- 192.168.2.204:80

On other Netgear routers you can set up 'custom ports' but not so on this model...despite being the top of the range Smiley Sad

Re: Port forwarding to different LAN servers listening in the same port

Dave - you seem to be missing the point - it doesn't make any difference what your Belkin can do, your Netgear cannot do it - Netgear does not need to match Belkin feature for feature, you on the other hand, need to do your research before purchasing.

Your options are simple - return the Netgear and continue to use the Belkin or use the Netgear and put the cameras on different ports (if possible).

Re: Port forwarding to different LAN servers listening in the same port

what is the point of opening a forum and listening to users if one does not like what the users are claiming ?

what is the point of calling this device a "router" if it does not fulfill basic ROUTING feature (PAT) ... ? ... and unlike almost any router (i can add D-Link model next to the Belkin mentionned above)

Yes hello...

... I bought a Netgear DGND3700 last week in US... unfortunately I brought it back to Paris where I live... I have more than 18 PAT routes needs to set-up at home (ftp and telnet to multiple home PCs and other linux boxes...) and when I opened the router, i coudn't believe that the router does not support this basic PAT routing feature (and yet i used 5 or 6 different routers so far in the past without even bothering).

I would never have thought that i have to check this feature before buying arouter (or I would have done it of course)

I called the seller to send the box back but the seller rejects to collect it from outside US !

what should I do ?

what Netgear is answering to users like me (and I found tons of us on the net, not to mention in this forum)

I am really upset !!!!!!!!!

Forum is user to user base

Every manufacture has different view. Not all manufacture has to be 100% same

what should I do ?


Not sure where your purchased from that this your responsibility to know your return policy is not accepted by its' term

Re: Port forwarding to different LAN servers listening in the same port

Thanks jmizoguchi but you are not answering the question... I let other readers assess !

why don't just join your voice to us and call for netgear to add this feature : i can provide the code !

for the time being i managed to solve most (but not all) of the PAT needs i have ! you know how ? by patching linux in several boxes i have ... it took me one days work and testing... that's i don't mind !

but i do mind that i have to do it again each time i upgrade my linux boxes !

and you keep sayiog all this is "normal" for 120 € router box ?

Re: Port forwarding to different LAN servers listening in the same port

A couple of points habib - routers were around long before broadband internet and the use of NAT & PAT - those are not basic routing features, they are consumer router features, specifically used when it is necessary to share a single public ip address amongst several devices.

It is the router manufacturer who decides what features will be offered in any particular product, and if Netgear chooses to offer NAT in a given router, but not PAT, there is only one thing that you, the consumer can do - don't purchase that router.

The onus is on YOU the purchaser, to research the product before purchasing it, to determine that it meets your needs - if it does, purchase it, if it doesn't you keep looking until you find something that does. Buying a product that does not meet your needs and then griping about it doesn't do anything other than waste money.

It really is that simple.

You have the code - great - find a cheap PC platform with dual NICs, configure it and use it as your router. You think more people need them - package them attractively and offer them for sale on the internet.

Make money, put Netgear out of business because you listen to your customers and they don't.

I guarantee you one thing - along the way you'll discover why Netgear does what they do, how they do it,

June - I chose not to delete your post - I want you to know it was edited and why.

This thread is going nowhere and I'm locking it - the same will be done for any unnecessarily argumentative thread I come across
