Have recently installed SolarWinds TFTP on my Windows Server and have opened the necessary ports in the firewall. When I attempt to connect over the Public IP Address after a few seconds i get the message "Dropped Because Pier Didn't Respond". It seems to only happen when the TFTP server is hosted. If I run internally, it is fine. I have increased the timeout settings and same results.
If anyone can shed light that would be greatly appreciated.
