Change port and host using .htaccess
.htaccess, apache2, mod-rewrite, portforwarding, subdomain
Solution
Playing with your rules, I found out that `HTTP_HOST` includes the port number. So the rules should look like
RewriteCond %{HTTP_HOST} ^sub.website.com:2000$ [NC]
RewriteCond %{SERVER_PORT} ^2000$
RewriteRule ^(.*)$ https://123.45.67.891:3000/$1 [L,R=302]
If you want to test against server name alone, you could use `%{SERVER_NAME}` as @faa suggested in the comments
RewriteCond %{SERVER_NAME} ^sub.website.com$ [NC]
Problem
I am trying to use `mod_rewrite` to basically port forward a port on a subdomain to another port on another IP. Like this: ``` sub.website.com:2000 --> 123.45.67.891:3000 ``` How could this be accomplished using a `.htaccess` file with `mod_rewrite`? I have tried the following but to no avail: ``` RewriteCond %{HTTP_HOST} ^sub.website.com$ [NC] RewriteCond %{SERVER_PORT} ^2000$ RewriteRule ^(.*)$ https://123.45.67.891:3000/$1 [L,R=302] ```
