I decided to run a port scan against my ASG (v 8.102) box from another location to test some things. I was surprised to find that it showed port 21 as open. I have two packet filter rules, one for remote web admin access and another that allows all outbound traffic from the LAN. Is there a setting somewhere that I can turn off? What am I missing?
