Alternative Port Forwarding without Router Config

[brotherbear]

I was wondering if their is an alternative method to portforwarding. Is their a DDNS client that can be installed on a computer and then be instructed to direct any traffic from abc.ddnsprovider.com:2101 to an 192.168.xxx.xxx .

Not sure what you are exactly expecting. Anything external with a 192.168.x.x reference will be invalid, and you would still need a port forward of some sort on your router to go to specific host anyway.
A lot of routers contain a DMZ function / Virtual Server funtion where ALL traffic gets passed to a certain host. Up to you to lockdown the host properly.

Or are you trying to get something working where you do not have access/ permissions to the router? Like a work environment?

[fandtm666]

you would have

xxyyzz.dyndns.com pointing to your ip then once it hits your
router you would configure the port forwarding there

external port 12345 directed to internal ip 192,168.1.3

Is there some reason why you can't port-forward on router? What is the problem you are trying to overcome?

[brotherbear]

I have an alarm system and cbus which interface with a Building Management System (BMS) and the network contractor refuses to open any ports so I access it remotely. I have setup a DrayTek Vigor 2920 and have WAN 1 as my ISP and WAN 2 the building network. So I want to port forward from WAN 1 to WAN 2 but I doubt that is possible so I am interested in a software alternative.

So you are trying to bypass a companies security policy.
It's asking for a world of trouble when you get caught.

Suggestion would be to do the right thing. Talk to the network guys, seldom have I been unable to come to some solution for remote access.

Its residential.

Its residential.

So that makes bypassing a secured setup O.K..
I see.

Sounds bloody fishy to me.

You are much better to obtain co-operation.

I am not familiar with the Draytek router you are using but had a quick look. The dual wan facility in the router seems to have been designed for connection to two ISP's for either increased speed or fallover capability. Port forwarding between the two wans has not been provided as an option in the web interface. It may be possible to implement such a configuration on this router through some other features available in the interface and/or through command line access but I know little about this router.

I don't know if there are other dual wan routers which support this feature. Likely it could be set up on a linux box connected directly to the two adsl modems.

I cannot, however, imagine how such a configuration can be set up without compromising the security of the Building Management System and any lan you may have set up.

Try reasoning with them again!

put teamviewer on the computer

[multiplexbow]

I agree.
Team viewer should work fine in this application and it will bypass all of the network security.
The other alternative is to use a 4G modem connected to the machine.

[warbo]

Give the network admin an uppercut. Some admins like to play god and are totally unreasonable when it comes to security.

As mentioned Teamviewer is another option if you don't get anywhere with him as it requires zero port forwarding.

[brotherbear]

Problem resolved. Bought a Netgear UTM from a Harris Technology Closing Sale for about $300 off and created a multi-homing network with DHCP turned off. It works out cheaper as I nolonger have to waste my time trying to contact the Network Management Company.

I see you've got it covered, I was going to suggest by Verigio. It's like I've always said - There is always more than one way to skin a cat
