[kwlug-disc] (IP/TCP) Port Relaying ... command is called what, again?

[john at vanostrand.com]

A proxy server is the thing generally use d for port 80. It, however, is probably the sledgehammer. Proxies can be big and require libraries and such. 

Net cat is useful for what you want and is lightweight. 

There are probably lots of options including some scripting that might get you through this.

I thought windows had "connection sharing" specifically for Internet but I figured it could work for vpn too. That does Nat.

Subject: [kwlug-disc] (IP/TCP) Port Relaying ... command is called what, again?

I'm setting up a (Open)VPN which by necessity is only point to point 
(machine to machine). Because that windows 7/8 machine won't nat 
(masquerade), there is no access to machines beyond that point.
(No access to premise routers so can't set up a port forward.)[Machine 
has cygwin installed and happy.] Bridging is an option, but I blew away 
my monthly 60GB Roger's traffic limit in 4 days when I was 
experimenting, presumably due to broadcasts. So, back to tunnelling, but 
no win 7 natting I've been able to find. Except for 
http://rusroute.com/, which I have no experience with to trust.

It occurs to me I only really need port 80 from another device on the 
network, all other requirements can be satisfied with this point to point.

So, it seems to me I only need something that will forward a port on a 
client's behalf. e.g. portforward localhost:8080 remotehost:80. Then the 
remote end of the link can just do http://othersideofvpnip:8080 and get 
on with their day.

(I know ssh will do all this for the port - I'm avoiding the command 
line / script weirdnesses with this particular user.)

So ... what's the command to use? netcat?

Netcat being a 'swiss army knife' (http://en.wikipedia.org/wiki/Netcat) 
seems a little like using a sledgehammer when only a wee tap will do it.

Other lighter options, or is netcat the beastie I'm looking for?
