I started a SQL Anywhere database server with the parameter -xs HTTP(PORT = 81). I also created a web service with a simple SQL statement. If I start this web service in the browser via localhost:81/dbname/webservice then I get the data. Everything great. Now I want to retrieve this data over the Internet. I set up the Fritzbox via DynDns, created shares, set up an Apache 2.4 on the database server (just to test access). Everything is working fine. Now I would also like to call up the web service via the Internet, i.e. via <call-up-URL>:81/dbname/webservice. I don't get any data. I carried out the port release, released the firewall for the ports and even switched off all security features for a test. No web service data via the Internet. but it works via localhost on the intranet.
