Is it possible to block all traffic from port _x_ from all hosts except one IP, but at layer2 using the EX3300's port filtering?
I attempted using the commands and GUI as per; https://www.juniper.net/documentation/en_US/junos/topics/concept/firewall-filter-ex-series-overview.html, but haven't had success so far.
Also -does 4 or 5 rules typically cause a very big increase in resources/CPU load?
Just want to make sure this is possible before I try again.
Any help appreciated. Many thanks.
