I had the same problem !

You could always use another open port on your work firewall. Port 443
springs to mind its for secure web pages and assuming you don't have any
of those just use your redirect method to port 2402.

Hope this helps

Subject: [slim] Port Forwarding public port 81 to 9000

This message is a bit off-topic (sorry), but I don't know where else on
the net to ask this sort of thing...

I sometimes (infrequently) steam music from home (WinXP Pro) to work. I
use the standard port 9000, but as the firewall at work won't allow the
use of this port, I get my router to port forward such that requests on
port 81go to port 9000.

This works fine. However, I would also like to access my home DigiGuide
service from work. This uses port 2402, which the firewall also blocks.
I use port 80 for accessing my home website, so I'm running out of ports
that I can forward.

I was wondering if I could do something within my web site (hosted by
IIS) such that I could set up pages that would redirect network traffic
to the desired service on their local port. eg. host a slim.html page
in IIS that would redirect to port 9000, and a digiguide.html that would
redirect to port 2402.

If I do a response.redirect(), this simply tells the client browser to
go to a different page, which won' work. I can't do a Server.Transfer()
to the slimserver port 9000, as this would need to be hosted in IIS.

A simple solution would appear to be to access the routers remote admin
pages, so I could change port forwarding of port 81 to the service I
would like to use. However, contrary to what my router documentation
suggests, remote admin doesn't work (Belkin ADSL wireless router, model
7630uk).

Has anyone else got any other ideas?

I've tried using the FTP port, but for some reason it didn't work. I don't know what ports are available through the firewall, and it doesn't sound like the best way of organising my network. But I'll try port 443.

Thanks,
