Software port switcher

I have a program which will only run on a certain port, but that port is blocked by my ISP. Is there such a thing as a port switcher program which would collect traffic from another port, f.e. 8900 and forward it to my application on port 89 and the other way around for outgoing traffic?

Yes, that's possible, but what OS are you running? I think technically it's against our rules to discuss this sort of thing here...

?!?
I think it's against the law to filter ports - it could be said, that the ISP intentionally modifies and/or destroys its users data, which is illegal.
@nutkenz - if you use Linux OS it would be very easy to do it - one single line of code

(Unfortunately?) I'm running Windows Vista on the client PC and Windows XP on the server.

Search Google for "windows port forwarding" software...
More info about it -

This -

It doesn't seem to work correctly though; I added the port 8900 to be forwarded to localhost:89, when I connect on
http://localhost:8900/ from the server, it works. When I connect remotely using hostname:8900 I do see the title of the page (FlexiServer) coming up though only when using Opera or FF (not IE7 - that one fails completely: 404), but there is no content... Any idea what could be causing this?

If you are discussing the circumvention of the rules of your ISP so that you can do something that violates their terms of service, that is against our rules here.
However, if all you are discussing is port forwarding, that is different.
PLEASE DO NOT USE OUR COMMUNITY TO FIND WAYS AROUND RESTRICTIONS PUT IN PLACE BY YOUR SERVICE PROVIDERS. That is not the purpose of our community and any post that does this will be trashed.

My ISP does not intend to block use of this program, it's a security measure to protect their customers. I'm not breaking any rules by using this program or forwarding the port...

Ok, I just wanted to make sure.

Port forwarding is a way to pass these restrictions - you, me and the ISP perfectly knows that. And it is legal.
I am a little bit sick of so called "
Internet Service Provider", that think that "Internet" is only web browsing, e-mailing and torrents. Indeed, there is no way an ISP could stop port-forwarding, so why they restrict the usage of low ports - simply because they want *money*. That's it...
If they, claim to make this for "protection", then how do they choose the ports to filter? Every new Trojan has different port to operate on ... So?
By filtering the low ports range (i.e. 1-1024) for home users, they just make you pay more, if you want to have a normal web services - that is, operating on the usual ports. One can always make a port-forward (and that
does not violate the user agreement) and have these services running, but that would be very uncomfortable for their users (i.e. web server running on port 8080).
I agree that there are ports which should be filtered (e.g. TCP/UDP 137-139, 135, 445) but they are really well known and a lot of exploits are available for services running on these ports. Yet, I think that anybody should be able to call his ISP and insist to open these ports.
And I don't know a user who hasn't installed a firewall on his PC ... That's for "ISP protecting users".
PS: Sorry, if I sound angry, but I am ...

Vlad, I do appreciate your sentiment. There are many things that I too have issue with when it comes to service providers (of any service, not just the internet). I just want to make it clear that our community is not a place to discuss ways to circumvent rules of these service providers, whether we agree with those rules or not.
We also actively trash threads related to pirating software, using pirated software or anything illegal in that arena. We do not want our community to be used as a place for people to come to learn how to violate rules.
I am not saying this is what is going on in this thread. In fact, I believe that you are not discussing anything illegal or in violation of any rules. I just want everyone in this thread to know the position of this community as it relates to assisting people in doing something they should not be doing. And that position is we vehemently denounce it.
PS It is perfectly OK for you to be angry. I have been there many times before. I am sure there are others that will totally be on board with your feelings.

Okay, now that we've determined I'm not doing anything which I shouldn't be doing, let's get back on topic

I'd vote for a router like the WRT54GL and DD-WRT firmware - It does what you ask in it's sleep.

I agree with Kieran Huggins - move to Linux router

I've found this -
http://support.microsoft.com/kb/309524 - I suppose you can forward any port this way in Windows XP.
