ATT BroadBand Port Blocking

> Here are my home network setup:
>        ATT Broadband connection
>        RCN cable modem
>        LinkSys Router (Model BEFSR41)
>        RedHat Linux 7.2 (on Compaq Deskpro)

For the problem of accessing the Linux box from the outside world, I just 
recalled that the Linksys router allows one to declare a "DMZ Host" computer, 
that in some sense is "more connected" to the Internet.  You might try 
turning that feature on.
