I would like to have advices regarding firewall rules. I'm deploying a PA-3220 on my main site (site A). On this main site, I have several zones configured on my PA3220 (user, servers, dmz Intranet,). I have also 5 remote sites.
I must create a rule to allow small sites and users & servers zone configured on my main site (site A) to reach our DMZ Intranet zone . What is the best approch to create a rule ? Is-it to create a first rule (wich rule name ?) to allow remote site to Intranet zone on site A and a second rule to allow the the local zone (user, server) to reach Intranet ?
Is-it to create a single rule with, in source zone, the WAN zone (remote site) and local zone (user, servers) and destination my DMZ network in the Intranet zone ? And is-it a problem if in source zone, I have a mix of WAN access (for traffic coming from my remote site) and local site (user, servers) for traffic coming from these local zones ?
