Open TCP Port 80 in Windows Firewall
TCP Port 80 is open for outgoing communications, by default, in most firewall software. In order to allow Port 80 open for incoming connections, we have to allow it from firewall. Steps are as follows :
Step 1 (opening windows firewall)
Open Control Panel > Windows Firewall
Step 2 (open advanced settings)
Select Inbound Rules in the left column of the Windows Firewall.
Select New Rule in the right column.
Select Port in the New Inbound Rule Wizard and then click Next. Note, do not create a Program rule – you must create a Port rule.
Select which protocol this rule will apply to TCP, select Specific local ports, type port number 80, and then click Next.
Select Allow the connection and then click Next
Select when this rule applies (check all of them for the port to always stay open) and then click Next.
Give this rule a name and then click Finish to add the new rule.
TCP Port 80 is now open and ready to be used.
