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.
