  1. On the inside of your router you would have a static (ie = 192.168.1.20), on the outside (often refered to as the WAN portion) = would by a dynamic, and you would use NAT and port mapping (IPnP) to = allow services from the WAN to your static internal IP.
  2. Mine works fine doing this...

  1. Your ISP dictates whether or not you can have a static IP or not. = It's not dependant on the fact you have a router. For that matter your = EnGuarde box can act as a router. Many cable providers do not offer = static IPs as is the case here in Toronto. For this, as already = recommended, you'll need a dynamic DNS host who polls the dynamic = connection from your ISP every 30 seconds or a minute, whatever, to see = if you've been assigned a different IP address or not.
  2. Same type of issue, most ISP will not forward SMTP or POP3 packets. = They will not route traffic through their own networks using port 110 unless = it's a request to an external POP server from within their network. If = that makes sense. As for the rest, FTP, SSH, telnet, most probably won't = work either for the same reason. Your ISP will not route that type of = traffic on its own network.

The only thing you may be able to do is setup a web site using port 80 = traffic only. That's not blocked by any ISPs, obviously. You'll even be = able to send mail from the box, like a formmail script or something, as = long as postfix uses your ISP's SMTP server. Chances are that this is = your issue =3D ISP limitations. If so, find and ISP that doesn't limit = traffic in one way or another. Good luck! Let us know how you make out.

I would definitely invest in a Cable Router, then you can have a static = IP on your box. Then just run a dyndns.org client, or some other = Dynamic Name Server...

I use a linksys and it works great.

I have read the manual and have followed the directions as = best as I'm able to understand (I'm a newbie)(...with big diapers). 1. = How may I setup my box since I only have cable Dynamic IP service?? 2. = What changes will need to be done for DNS to work properly?? 3.
