Technical Tip: How to allow an website that is being blocked by DNS Filter

[vifi]

Description	This article describes configuring DNS Filter to allow a website that DNS Filter blocks.
Scope	FortiGate v7.2.
Solution	Sometimes a website is blocked by a DNS Filter. Example: https://accounts.o2.co.uk/ is blocked by DNS Filter. The category to which this website belongs is allowed in DNS Filter. However, the website gets blocked. Perform a nslookup. C:\Users>nslookup accounts.o2.co.uk Name:    d3c17wgn4zp1k7.cloudfront.net Addresses:  18.172.153.90           18.172.153.59           18.172.153.12           18.172.153.33 Aliases:  accounts.o2.co.uk           lbprdcachetieraccountsproxy.o2r53ctp.co.uk           lbprd0cachetieraccountsproxy.o2r53ctp.co.uk    Configure the DNS Filter profile. Note that adding only 'accounts.o2.co.uk' is insufficient. The other hostnames that are related to this website should be added as well. The same logic could be applied to other websites when facing this issue.
