>getting 2 dynamic ip addresses</H3>
<p><strong>From Christi Gell
</strong></p>
<p align="right"><strong>Answered By Mike Orr
<br></strong></p>
<P><STRONG>
I have a DSL and I want to get 2 dynamic IP addresses w/it. I've got a
hub, but every time my husband needs to get online, I need to release my
IP address.
</STRONG></P>

Your hub is connected directly to the DSL modem? In that case, you will
have to contact your ISP to get a second dynamic address from them... if
you can.
</BLOCKQUOTE>
<BLOCKQUOTE>
A more common scenario is to have one computer (the server) connected to the
modem and also to the hub. The second computer is connected only to the hub.
The first computer has IP firewalling and IP masquerading compiled into the
kernel. (I assume you're running Linux, since you sent this to a Linux answer
forum. If you're using Windows, you'll have to go somewhere else for help.)
Then you enable IP masquerading on the server. Now the second computer
can reach the Internet without needing a second dynamic IP from the ISP.
</BLOCKQUOTE>
<BLOCKQUOTE>
To set this up, search for "masquerading" or "masquerade" in the Linux
Gazette search engine (<a href="http://www.linuxgazette.com/search.html"
>www.linuxgazette.com/search.html</a>). Or pick up a Linux
configuration book from the bookstore or look in the manual that came
with your distribution.
