I've never had much luck with 3Com and Linux (specifically their 509's). 
  The Netgear FA/311's have worked flawlessly for me though.

Are you wanting to set up the Linux box to do routing, or just want to 
get it online?  If it's the later and the Verizon modem is a Westel, 
just set your network connection on the Linux box for DHCP (the Westel 
/should/ handle it).  By default my Westel has most ports blocked, but 
you can do forwarding (NAT) via the web interface for the modem.  You 
won't need to do anything like that for surfing the web or checking 
email though (you'll have to do it for Bittorrent).  Depending on the 
security settings on your Linux box, you may have to open the port in 
that firewall (in /etc/sysconfig/iptables (if this is where it's located 
on your box) or via the GUI).
