Invalid Address When create white list rules

[ifs.snort () ptbig id]

hello,

I'm new with the snort. My office want to use snort for the firewall the 
configuration is inline between the modem and the mikrotik 1100 router. 
Everything is run well until WFH happen.

When WFH most of the team using anydesk. so I created the White List 
Rules but anything that I configured its always tell Invalid Address and 
nobody can access the anydesk. So I have to bypass manually. what should 
I do to make the firewall working?

thanks.
