I got your problem like this you want to add server using external IP but don't want to announce it.
External IP problem:
When port forwarding check the internal IP / device the port is forwarded to. If multiple devices are connected router acts as DHCP and allots different internal IP addresses to device. This is the reason server was online 3H. After that you probably rebooted the router or changed device which causes the internal IP to change and you can't get a ping on that port. I suggest to reserve a Internal IP address to your PC's MAC and then use that IP during port forwarding.
Announce:
In server.cfg set announce to 0 to disable it from showing in internet list.
Note:
Ping the server IP on forwarded port and post the reason why it is not responding like timeout / refuse connection etc
