This example shows you how to redirect incoming http requests to a machine on your
internal LAN. You could also use this method to redirect telnet, ftp, etc. The www
uses the http protocol.
I run MS FrontPage 98 on NT1. I wanted to redirect http requests from the gateway
machine to the web server on NT1. It was pretty easy, but a few hurdles along the
way.
Please note, that this was for my testing and education only. I don't intend to
continue to redirect such requests. But I wanted to try it. Just to see.
Eventually, I plan to add http to my gateway machine as yet another place to
publish my webpage.
Looking at the natd manual, it
shows that redirect_port is the command line option to use. I added the following
line to my natd.conf file. Please note, the IP address has been changed for security
reasons.
redirect_port tcp 111.222.333.444:80
redirect_port ucp 111.222.333.444:80
And I tried to access the page from my own subnet. But I couldn't. So I
jumped on EFnet IRC Network #freebsd to verify my solution. I received confirmation that what I
was doing was correct. And to as a test, it was suggested that I get an external
shell and try that. External shell? What's that?
In the end, my helper asked for the URL and they tried it. No luck.
Brain wave!
Filter rules.... kill the filter rules. I cleared out the filter rules and asked
him to try again. This time, success! |
