ZScaler ZPA issues using NSLOOKUP with work

[ccasola]

Hello all,

Im a bit new to PfSense Firewall. I currently just use it for ad blocking PFBLockerNG and web filtering with CloudFlare.

Recently my work is starting to migrate to ZScaler ZPA VPN. So far so good except when i went to use NSLOOKUP today. It resulted in the following screen shot:

I did a little research and found an article suggesting i disable DNSSEC and DNS Forwarding. I tried both but neither solution worked.

Has anyone else ran into this issue and if so, how did you resolve it?

Thanks,

Carlos
