Forums Connection Issues Porting for mirc.

I have been told that for dcc to work properly i only need to open server ports in routers.
We use omenserv as a server on our network.
I have always believed that we needed to open the following in order for mirc to send and receive properly,
59 113 6667 to 6669 and we use 1024 to 5000 and or 10052 to 10070 for dcc.
Has mirc changed that or was i misinformed or am i partially right or completly wrong.
Please help me straighten out my confusion.

You are partially right/wrong.

If you want your ident server or an ident response to succeed (on connecting to the IRC server) you need port 113 (by default) open. This is (probably) NOT really needed.

If you want to successfully SEND files via DCC then you need to forward the ports set in Options > Connect > Options > Advanced with the DCC checkbox checked. In your case 10052 through 10070, though you can make this range smaller since I doubt you'll ever have 19 DCC send events going on at the same time.

If you want to successfully RECEIVE files via DCC, then you have to make sure the other person/client does what I mentioned above.

To expand on 5618's reply, port 59 is commonly used for reverse DCC and is only needed if YOU are trying to receive *from* or connect *to* a person using reverse DCC on that port. It does not need to be open to send anything. 6667 is a similar situation, at least in regards to the Invision script and I'm sure 6669 is also similar. In the case of reverse DCC, you should get a message stating to type a /dcc command before connecting that will have a port number in the command. That's when you know you need that specific port open. It's rarely necessary, though.
