How can i make a network rule that makes only ordinary internet browsing in port 80 posible, and nothing else. (to tjectk if it is http is maybe not nessesary, just tcp/ip).
I dont understand that if i apply this rule:
“BLOCK and LOG TCP or UDP IN or OUT FROM IP [Any] TO IP [Any] WHERE SOURCE PORT IS 80 AND DESTINATION PORT IS 80”.
Then it is still posible to browse using Internet Explorere.
(I know that the rule in 2 is oposit of my question 1, but i still don´t understand why this rule is not working as I exspect).
Thx if someone can give advince, Anders, Denmark.
