I have a web server, which was working fine. It also was an FTP server and a Windows Remote Desktop server, all working fine. Someone called our ISP to increase the internet speed, and suddenly nothing works - I can connect with Teamviewer, but HTTP, FTP & RD doesn't work.
- Disabled firewall.
- Ran Wireshark - the packets don't come through at all.
- Set the webserver to port 20111, in case the ISP is blocking port 80, and again, the packets didn't come through at all. (localhost:20111 works fine)
- Port forwarding is set up for ports 80, 21, 3389 & 20111 to 10.0.0.32 (which is the correct address - checked with ipconfig).
- Restarted router and computer.
I would be very grateful for any help.
