How to block SMB1 and allow SMB2 and 3 on Firepower

Howzit Legends, 

 

So finally after 3 months of a massive learning curve on Firepower, I was able to replace our internet PANs with Firepower. So far there has been a couple hiccups, though we are getting through them. 

 

One that i'm unable to find any details on is how to seperate SMB version on FMC, it only recognises it as Netbios-SSN (SMB). This has stopped some services from working and I had to create a rule to allow 'all' SMB through the internal network. 

 

Is there a way to 'tag' the different SMB versions via firepower? 

 

Thank you

Heino
