Port forwarding

Anyone know of a router that can forward https from internal static IP on port 5001 to external port 443 and vice versa?

Perhaps I am going to have to configure a linux box...

home or business?

most non ISP locked routers have full NAT tables you can config

home - it's a netgear dg834g with the
V4.01.40 - DGTeam Rev. 0849firware

it is supported on your current ADSL modem/router so download the manual


see page 3-6


Edit, whoops looks like it does not support port changes though. time to buy an up to date box me thinks

Even the latest netgear doesn't do it, but everything else does, so its in the post!

Well my Netgear FVS558 does support it, but then again it is not an ADSL wireless device. There is something to be said for splitting functionality, although it will obviously cost more. For my bother business, I established his connection as a standalone ADSL modem, connected into a Netgear FVS338. That way he could get AES256 VPN encrytion with me and his staff homes.

He did suggest that there was a need for wireless in his office, but as the first thing he would do is take his laptop out the cupboard and drop it into a docking station, he soon realised there was no point.

The company I work for also provides all staff supplied with laptops with proper docking stations, keyboard/mouse and monitor. So nobody anywhere needs wireless and corporate policies disable it.

our office draytek vigor 2600 definitely does do port changes in its nat table. However it will only accept a destination IP that is on its own subnet. So I've still had to sit a linux box behind it to redirect the IP addresses to where I want them to go. Linux boxes rock. Linux boxes can do anything

We have a netgear one like yourself, and it doesn't do the port changes. Also the D-Link one here doesn't do port changes either.

I think that Tim is getting PAT and NAT mixed up - it IS a dissapointment that the Netgears dont do it.

I had a really cheap (and ultimately rubbish in other ways) router that did it.

You could always stick a hardware firewall inline to do it.

I agree on the linux boxes can do anything argument - I even stuck an ADSL card in one and cut the router out all together - didnt make much sense to do in the ling run tho, hugely overkill for what I was doing

Been doing networking for far too many years for that mistake. I built my first on a star lan back in 1981 to connect a group of rockwell Aim 65s to an Acorn Atom acting as a file server. I did some work on CSMA/CD and XNS networks in the mid 80s writing device drivers and was an early implimentor of TCP/IP. In fact we got a full class B allocation (159.245.0.0/16)

I need to post a screenshot just to prove my netgear does it. Please wait






This firewall rule shifts incoming SMTP traffic from BT ADSL users to a postfix filter I am running on port 10025..


Is this not PAT
