Thanks for your reply, But I must be thick headed this morning, because what you say below makes no sense to me. I checked out the 2 referenced descriptions and they say nothing about doing nat. I have Lan with private ip address that send packets to public internet. How does an proxy server solve the private ip address versus my public ip address problem? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of jan.muenther@nruns.com Sent: Monday, February 02, 2004 11:28 AM To: JJB Cc: Jorn Argelo; questions@freebsd.org Subject: Re: proxies and firewalls > Are you saying you know of an proxy server that does the nat > function? Actually, the point of having proxies is *not* having to route. Your proxy machine should not be able to forward packets. Roughly, there a two different sub-groups: Circuit layer and application layer proxies, names should be self explaining. Example for an app layer gateway: Port: fwtk-2.1 Path: /usr/ports/security/fwtk Info: A toolkit used for building firewalls based on proxy services Example for a circuit level proxy: Port: nylon-1.2 Path: /usr/ports/net/nylon Info: A Unix SOCKS 4 and 5 proxy server Socks5 is already app layer, too, IIRC.
