We recommend granting full Internet access, all ports, to Connectifyd.exe in order for Connectify Hotspot to function properly. If you unblock all of the above ports, Connectify Hotspot itself will be fine, but a firewall may still prevent Connectify Hotspot from routing traffic to and from the Internet. In addition to the above-named ports, if your firewall software has any settings involving Internet Connection Sharing (ICS), please enable support for these. The ports are used for UPnP (Universal Plug and Play), DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) services. Connectify Hotspot uses two kinds of ports, UDP (User Datagram Protocol) and TCP (Transmission Control Protocol), both very common Internet low-level protocols. A port is like a channel on the network, different applications use different specific channels. Next, you probably need to open ports in your firewall.
This is because Windows already trusts Connectify Hotspot. When you’re using Microsoft’s own Windows Firewall, Connectify Hotspot can usually configure the settings for this. To get Connectify Hotspot and your security software to cooperate, you must get Connectify onto the security software’s white list. The white list is a list of trusted programs or other resources. Included in every kind of security software is some kind of a “white list".
Security software, once installed, is completely in charge of other programs. Security software of any kind (antivirus, firewall, combination suites, VPNs, etc.) is specifically designed to disable all kinds of normal functions in Windows. How do I configure my firewall to work with Hotspot?
