I looked at the rules and noticed that quite often tcp flag set to flags:A+
I used to think that tcp flags were:
SYN (s), ACK (ack),  FIN (f), RESET (r), PUSH (p), URGENT (urg), and
Placeholder (.).

What is A+ as tcp flag? Are there any others I'm not aware of?
thx.

A is ack; + means ACK plus anything else.
