    OK, but the nice thing about the source-based rule is it's not very 
    likely to drop legitimate traffic (unless you misconfigure it without 
    any sense of your normal traffic profile), whereas a destination-
    based rule could easily cause that problem, particularly for public 
    servers.
    
    
    On a slightly off-topic note - do you find ScreenOS stable?  I 
    avoided it for stability reasons at a newly-deployed site but it 
    would have been convenient to start off with it because when the time 
    comes to upgrade it looks like I'll have to re-architect lots of the 
    rules to adapt to its new syntax.
