Getting the block Skype with norton internet security.

Hello, I am suffering from block skype with norton internet security version 19.7.1.5 from which I can’t access the internet to talk by skype. I have tried the disabling norton’s smart firewall. Then skype could get to the internet with own defaults settings. However, that could be dangerous to leave my pc without protection, that is why could anybody say which settings and where to change to make skype accessing to the internet with active Norton smart firewall?
