Hello together,

I want to keep the ServerName and Port dynamicly on my rewrite: Lets say the Firewall redirect port 8081 to 80. So, if i access the webserver for example with "192.168.1.123/frontend" or "my.domain.tld:8081/frontend" i should be redirect to "192.168.1.123/frontend/" or "my.domain.tld:8081/frontend/"

If i use the normal redirect rewrite ^(.*[^/])$ $1/ permanent; and i access with the port 8081 the port got removed. (I already tried port_in_redirect
off;)

When i acces with "my.domain.tld:8081/frontend" (without slash at the end) i got rewritten to port 80, but port 80 is not open in the firewall, and if i access with the slash at the end everthing works. So somewhere nginx removes the port. And yes, this is the server because i got a new entry in the access.log.

I use almost the default configuration:
server {
listen 80 default_server;
listen [::]:80 default_server;

root /var/www/html;
index index.php index.html index.htm index.nginx-debian.html;

server_name _;
rewrite ^(.*[^/])$ $1/ permanent;

location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}

location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
}

Thank you in anticipation!
