I've been whacking away at this for more time than I care to admit, but I just can't seem to get it to work. My overall problem is with the device certificate and making it work across my various devices so I can turn on HTTPS scanning.
I have an XG firewall working on a small non-domain network. The firewall is named "fw" and is addressed at 172.20.1.1. Firewall DNS configuration is configured to look for resolution via CloudFlair DNS servers (22.214.171.124 & 126.96.36.199), and my local devices point the firewall (172.20.1.1) for their DNS resolution. I also have a DNS host entry for fw which points to 172.20.1.1. NSLookup of fw correctly returns IP for fw both from the diagnostic menu on the firewall and from a command prompt on one of the client workstations. Public website host resolution works perfectly.
My issue is that no matter how I configure it, I cannot ping the host name of the firewall from another device. IP yes, host name, no. The zone is configured to allow PING and DNS. What could I possibly be missing?
