Linux port forward or redirect question.

JackL92 · 06-04-2011, 06:49 PM

I have a VPS and a Webserver(different host), both of them are linux.

I would like to redirect port 80 from my VPS to my Webserver, however, I can only use domain to as my webserver address.

For example, if I type my-VPS-IP into IE, my VPS will forward/redirect my IE request to my webserver.

How can I do this and thank you!

Couldn't you just do this using your .htaccess file?

I think something like:

Code:

RewriteEngine on
RewriteRule ^(.*)$ http://www.webserver.com/$1 [R=301,L]

would work. However, if I've misunderstood what you're asking, do correct me

Hope this helps,

OOps, forgot the mention, without web server.
It takes too much RAM to run a web server for just redirecting users to other sites.

Hello,

I have 2 solutions:
1) use iptables https://adminuser.wordpress.com/2008...sing-iptables/
2) use netcat:

Code:

nc -l -p 80 -c 'nc www.google.com 80'

Be aware that with netcat you will have a quick and dirty solution. Moreover, you will have to respawn the command after each connection to port 80.
So if you want a clean solution: choose iptables one.

Kind regards,

Hmm, the iptables one is the best, however, it cannot redirect to domain.
There are may traffic I cannot stay infront of my computer for the second solution respawn the command after each connection to port 80.

I guess this is almost to impossible to redirct with domain.

Why can't you redirect by IP but just by domain ? You do not have a static IP ? or you are in complex architecture where one domain may refer to multiple IP ?
Anyway about your problem, I think that with a good script based on netcat approach, it is do-able.

Best regards,

cuz my web server have multi-domain host on it. the server can only get you to the right place with domain.
I guess ill install apache(httpd) instead, hopefully it wont take too much RAM.
