.htaccess port rewrite for subdomains – Apache

I am trying to redirect all SUBDOMAINS, except portal.example.com from any port (usually it’s 80 or 443) to port 30000.

e.g.

  • example.com: (any port) shall have no change
  • www.example.com: (any port) shall have no change
  • portal.example.com (any port) shall have no change
  • a.example.com (any port) shall be updated to a.example.com:30000
  • b.example.com (any port) shall be updated to b.example.com:30000
  • *.example.com (any port) shall be updated to *.example.com:30000
  • etc.

I currently have following .htaccess, directing example.com and *.example.com without change:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

    A bit refactored rule:

    RewriteEngine On

RewriteCond %{SERVER_PORT} !=30000
RewriteCond !^((?:www|portal).)?example.com [NC]
RewriteRule ^ http://%{HTTP_HOST}:30000%{REQUEST_URI} [R=301,NE,L]
