RE: Accept IRC DCC Send and Receive

Hi Richard,

Sounds good on paper, but does it really work? I have no use for IRC, so
I don't use it and don't intend to. But if you've tried this out and
know that it works, I'm willing to put mIRC on a VM and work out the
steps for a tutorial.

Thanks!

Tom

It's not impossible.

DCC Get connections are a TCP inbound connection.  What you'll need to
do
is to publish the relevant client machine (ie the PC that mIRC is
running on).

I would suggest configuring mIRC to use a restricted port range, and
then use
a server publishing rule to redirect inbound connections on those ports
to that
client machine.  Then you will probably want to put some firewall
software on
that machine to make sure that those inbound connections only go to the
mIRC
program and not to anywhere else.

Have fun!
