Ok here's the big question lol

Setup a VPN server so I can use my shares and VNC when i'm out and about over HSDPA over my mobile when I get bored (at my old workplace) from either of my laptops or PDA - worked very well for over a year.

BUT my new work place is a little remote and there no phone signal here I may get lucky and get the odd single bar but still that's not good enough for GPRS to work well.

Fortunately they have wifi here but anything other than port 80 and 433 that i've noticed so far is firewalled so no VPN traffic can get through (i'm using ptpp as my PDA only supports this without using 3rd party resource hogging clients)

Now my question i've been trying to solve is there a way using Windows Server 2003 built in VPN client to remap the port (i think its at 1327 or something atm) to 80 or 433?
I've looked around in Windows server and nothing grabbed my attention, but i have a few ideas.

Firstly if my router supported certain NAT features I could forward outside port ie 80 to a different inside port say the ptpp one and it would work a treat.... my Linksys one could do this but it died and got replaced by a netgear that cant.....so option one is replace my pretty white Netgear with purple LEDs that id hate to replace - also there's no current working openWRT firmware for it so that's not going to work.

Secondly actually changing the port in the Windows software (which I cant figure out how to do server side if you have any ideas please shout it out!) I will consider other VPN clients if they are decent and stable and will support windows mobile 5, OSX and XP and can change their port. I can already change the port client side by simply putting :80/433 on the end.

and Finally which I have yet to test is from what I understand on the actual VPN server forward anything that is sent to port 80/433 to the VPN port on the same machine using the netSH command (http://www.eggheadcafe.com/software/aspnet/31829724/port-remapping.aspx)

Any other ideas or pointers will be very welcome, anything at all other than ask the admin to open the port for me lol

Thanks , Shawn

I was going to suggest OpenWrt ... :( ... it's the perfect solution for things like this.

R-ow-ter. (Row-ter looks like Row[your boat]-ter. It's more like R-ow[that f'ing hurts]-ter).

Roo-ter sounds like you have a plumbing problem. :P
