My mistake! On IPFire (running NGINX) port 80 was closed. Now I'm a little closer. With:


worker_processes 1;
events {
worker_connections 1024;
}

http {
server_names_hash_bucket_size 64;
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
server_name gw.mydomain.com;
location / {
proxy_pass http://192.168.24.109;
}
}
}

I can connect from the outside to the web server :-) What surprises me however is that in the address line of Firefox my external WAN-IP of the firewall is located afterwards. Is this normal an ok?
