The ident thing is partially true.  EFnet (the network I use), does claim 
to require ident.  If you actually look though, it initiates the 
connection, before it sends out it's ident request. 

I am not concerned at all with dcc.  dcc was a huge mistake and should've 
never been implemented into irc. 
I am, however, interested in the nat irc handlers.  Where do I get them 
and how do I use them? What're they for?

Regards,

Tim

Indeed, however I assumed that anyone interested in the security of having 
a 
firewall wouldn't be using insecure things like DCC.   However, your 
reminder 
that there is a conntrack helper for this protocol is a good one.

You mean they actually require an identd response before allowing a 
connection (rather than just making it take a bit longer than usual)?

What's the point in that?   It adds nothing to security, adds very little 
to 
logging opportunities, and only interferes with people trying to keep 
their 
networks to themselves.

Ho Hum; it's a strange world on the Internet....
