I have added a really simple firewall rule for testing, on the Security - Firewall rules page. The rule is below and the Action is Block, but I can still visit the host listed in the rule. Am I missing something obvious? I waited a bit to see if there is a delay in the rule becoming active. Thanks
Thanks for the reply, following your suggestion I discovered a rule under " IP Access Rules" for the IP address of my office which was allowing all traffic from my IP!
