The person didn't say he was using FTP.
Man, tell me something I don't know.
And if you know exactly what you're doing, you don't need one running behind a border device.
I never said that NAT was a security feature. A router is a border device that acts in a FW like manner that is using NAT, and some even with SPI, which separates two networks. And then there are packet filtering FW routers that this OP has, which is a WRT54G router.
You forget that I have been in this NG since 2001, and I have talked with and taken the advice of the best in this NG. Please man don't talk to me about this, as I already know. In a wireless situation like this person has, I would us a packet filter behind the router.
I don't run with packet filters on my machine behind a FW appliance. It's as simple as that, and I wouldn't do it for some routers either. It's a simple as that.
The OP can do what he wants. It's his network and not my network.
Please man, what you are talking about to me is pointless.
I am not here for a debate with you or any argument about this, that or the other, and you need to stop or slow your roll on this, because I am already tired of it.
