Cisco Firework 1120 - FQDN Resolution

[tainarapedrosa]

Hey guys,

I have a client that has deployed Cisco Firework 1120 in its environment. We're implementing a SaaS solution in their environment, which must have incoming traffic released by the FQDN. There's a limitation because it works with packet filtering, that's, based on IPs. Is there any way to perform resolution by FQDN to filter traffic through access control rules or pre-filter policy? A firmware update, for example?
I found these two technical notes, but I don't know if they cover the model they have. Can you help me, please?

They even opened a ticket directly with support, but I don't know if they effectively explained the need.

Thank you =]

Yes, using FQDNs in an ACL is fully supported as of release 6.3 - which is quite old by now (first released in March 2020).

The Firepower 1120 requires a minimum of release 6.4 just to operate. 7.2.5 is the current recommended release.
