I think that I can use the first one as a router/proxy server and route all
the local requests to it. Anyone have any experience and advise?
Thanks!

Matt,
There is one problem that arises after doing that.
I'm not on IP Chains (still 2.0.35), but when the modem makes its connection, it
gets an IP for the dial in side; and replaces the default route to route
everything via the modem link.
The result is that, yes, the other machines can masquerade though the box with
the modem to the world; and, yes, the other machines can telnet to the box with
the modem - but the box with the modem can't telnet to the other internal boxes.
- no route to host.
Any thoughts on that part of it?
Thanks for and advice on this.
George.

]There is one problem that arises after doing that.
But I was mistaken. Sorry Matt.
My previous post was wrong. It was a local config problem.

My personal experience is that IP masquerading works most, but not all of the
time.
For shared Internet access running a proxy is much better. Try Squid, it works
great for me!

WinProxy uses NAT (Network Adress Translation) and is not only a proxy.Quote:> I've used a proxy server in a Windows LAN, and I've recently installed a

The way a typical web proxy server works, your web browser (lynx,
netscape...) must be told that your are using a proxy server, and
what its address and port number are.
Proxy servers for other protocols exist, I believe, but I'm not
familiar with them.
Then there is SOCKS, which is a similar concept carried to almost
any protocol, but again, your client (like telnet, ftp, rsh,
whatever) must be "SOCKS-aware" to be able to use it.
When you use IP Masq, the outside world thinks all requests are
coming from the gateway machine itself. So even if you have 255
machines inside your network using IP addresses from the private
IP block, the outside world doesn't see any of them. The
advantage is that, as long as the routing is setup correctly, your
"clients" need not be any different - they actually think they're
talking directly to the outside host, and in a way, they are. A
bigger advantage is that you need only 1 "real" IP address for a
whole bunch of people.
NAT, I believe, is similar, except that there is a 1-to-1
correspondence between IP addresses on the inside and those seen
by the outside world. So you need more "real" IP addresses. I
don't know more than that.
Hope this helps.

1. HELP - using Linux box as Router/Gateway.
Hello Linux world,
I would like to use my Linux machine as a gateway between two subnets
of netmask 255.255.255.0. I have installed two ethernet cards and modified
the kernel to recognize both the cards. Is there any software, like gated
for linux to route between these interfaces.
Also if anyone has used linux as gateway, let me know how efficient/reliable
it is?
btw, I am running linux 1.0.8/slackware on a 386, which I installed 2 days back.
If anyone could help me, please mail me and I could give you more details.
Thanks in advance.
Mahesh
