I was wondering why a simple firewall rule allowing inbound connections to some executable just would not work.
Extensive troubleshooting, excepting disabling the firewall (works), attempting relaxing any other conditions, like removing port restrictions (doesn’t work), source IP/subnet restrictions (doesn’t work), and a whole bunch of other stuff just simply did not work.
Finally frustrated, I just tried removing the targeted/allowed executable – port, source IP/subnet and other bits in place… WORKS.
WTF?
