Friends I have the following Cisco DPC3825. Enter the settings and put in the DMZ web server that I have, but when I try to access it from another network I get the error code 504, which is the gateway problem. I can access the server via ssh without problems. Research on google for 3 days and can not find the solution to my problem. This router is different compared to the ones I had. The IP to access my router via web from the local network is 192.168.100.1, and the IP of the server I put in the DMZ is 192.168.0.17. No other information could you provide to clarify my problem.
