UGN Security Forums UGN Security: Knowledge Base Operating Systems Windows & Windows Security Making a router

I have a small network which connects to the internet thru a proxy server running winXP. The proxy supports http/ftp/etc, and some gateways too (FTP/telnet). The problem is routing will only works for these supported protocols. What if I want to be able to use all 65535 ports that is not only as request to all ports, but also being able to serve (perhaps).

Essentially it's turning my winXP box into a router right? Is that possible. Software-wise does something propose this feature?
I have tried port mappers but they only allow to pre-define to certain hosts and ports, no *real time* work :-(

thx

It's possible, but it wouldn't be easy. You'd have to hook the adapter to route it. Of course an application can't setup servers on every port. I don't know of any software that does this.

However hardware routers do it all the time. Go buy one. My linksys switched 4-port router with a built in firewall only cost me $60.

Take a look at www.sygate.com and snag a copy of their business connection sharing software. "You can snag a crack for it at http://www.astalavista.box.sk but only use it for educational pourposes until you decide to purchase it"... :x

"You'd have to hook the adapter to route it."

I don't get it SilentRage.

as for the hardware router..I just posted before (i'm in africa) ..no way I'm gonna find a router :-(
except for my isp's one lol

Don't worry about what I said about hooking the adaptor. If sygate does what you want, then it will do all that low-level work automatically and you won't need to know a thing about it.

For pure interest's sake, I guess I'll explain hooking - even if you may never use this information:

Normal Behavior:
Data gets passed from your cable line to your ethernet card. Then it is passed to your ethernet adapter, then to the operating system, then to the relevent program.

When you "hook" something, you insert yourself into the chain of events so that it would be like this:

Data gets passed from your cable line to your ethernet card. Then it is passed to your ethernet adapter, then it is passed to the hooking program, then the program may CHOOSE to pass it to the operating system, which will then be passed to the relevent program.

So by hooking into the chain of events, you may log or even filter the pass-thru data.

This is how software firewalls block connectivity.

right, so essentially this could be done coding my own firewall...
and apparently, that's been done (says gizmo).

k i'll check that sygate thanx. BTW SilentRage Africa's will, i'm still on 56K :-(

Well, there's dial-up adapters too.

Data moves much the same way:
Internet -> Modem -> Adapter -> OS -> Program
