Problem: the laptop does not connect to the computer via the web socket. Port 8889. Through localhost everything connects. Through LAN at least kill, do not want. In the firewall, the incoming connection is not displayed at all (on the outgoing laptop is displayed, it does not blot, but 0 bytes are transmitted). I created the rules, already cut the firewalls on both sides, nothing helped. Firewall windows off.
WTF? Where else to dig for further diagnosis?
Systems: on a computer (where the webserver) - vin7 x64, on the laptop - vinHR sp3.
