firewall/connections - what does the first column mean

Hi,

what does the first column in firewall/connections site mean - SAC, SACs, A, U?

[admin@] /ip firewall connection> print
Flags: E - expected, S - seen-reply, A - assured, C - confirmed, D - dying, F - fasttrack, 
s - srcnat, d - dstnat

Thanks - I should use the CLI more than the winbox tool :wink:

Winbox can show you explanation as well - just keep mouse on this column and see popup.

Didn’t know, thanks :slight_smile:

Cool :wink:
