- Then I assume you don't have Xwindows or the like else you would limit the
- range of the reply addresses. Beyond that, you can firewall things with a
- server on the "outside" of the firewall to handle all gateway traffic and an
- internal server to handle stuff inside the wall. The external gateway would
- have to be an MX router of sorts and permit typical traffic such as Telnet,
- and FTP.
-
- What I would like to see is a router/gateway that is smart enough to know
- what the new outbound packets are issued at and allow them to pass, even if
- you have a filter. (sorta like giving it a priority/security level to pass)
-
- With an external box, you can tell your router to accept anything from it but
- ignore anything else....persay....
