That's one description of the problems one sees with firewalls that 
have reflexive ACLs installed - outgoing traffic on a port enables 
incoming traffic on that port. Since rat uses the same source and 
destination port, it will work properly. Vic uses different source and 
dest ports, so the traffic won't flow back in.
