Hi, I'm programming an IRC bot. I'm trying to establish a dcc
connection with another IRC client. I give the ipaddress and port
number to the client in the request. I listen to that port with
TcpListener on IPAddress.Any. The listener never receives a
connection.
My situation is the bot computer is behind a router. Is there
something special that must be done to bind to the router's port?
Thanks,
Sean.

You must enable portforwarding for that specific port on your router. If you
don't packets will most likely arrive at the router and just be dropped.

How is it then that MIRC on that same computer can initiate and accept
DCC requests? I'm just trying to do the same thing as MIRC with
regards to DCC CHAT.

If it's a router, and there is no network address translation occuring,
then the packet should just end up in the right spot. You might find it
useful to run a packet sniffer on the Internet side of the router to
diagnose this. Ethereal is very nice (http://www.ethereal.com)
You must enable portforwarding for that specific port on your router. If you
don't packets will most likely arrive at the router and just be dropped.
If you have network address translation happening, or the router is a
firewall, then this is correct. Some of the nicer firewalls will do
connection tracking to make this work transparently.

Bah, I don't quite get this yet. MIRC can initiate and accept dcc
requests behind the firewall just find.
Thanks for the sniffer link.
I tried it out, but can't seem to put it all together yet.
MIRC sends 2 requests through irc: 1) notice message, 2) privmsg. Both
are pointing to the ip of the cable modem and the same port. Then the
irc initiater sends an accept after accept is clicked, and the MIRC
sends an ack back.

hi newsgroup,
I'd like to connect to a remote DB2 Database V 8.2 using the "DB2
Steuerzentrale" (I guess it's called something like "DB2 management console"
in the English version). Since the database host is behind a firewall I
tried to communicate through ssh port forwarding.
Therefore, I run:
ssh -L 6789:remotename:6789 -L 50000:remotename:50000 -L
50001:remotename:50001 -L 523:remotename:523 remotename
