DCC not working behind a router??

[Flyer79]

Hello there

I got a router from Belkin set up in my place....so one of the things i noticed is that is was blocking my DCC....sending and receiving.

I´ve changed de ports that my IRC uses to use only 1024 one and told the router to open that port on TCP and UDP basis....but i still cant get it done...

What gives??

Sorry for my ignorance. What is DCC? Do you mean Domain Controller?

[AzKidd69]

direct client connection.. it's a file transfer protocol for IRC ( you know the first instant messenger for the masses)...

I know these instructions are for MIRC.. but it should give you an idea on what to do..

hes talking about file transfer in IRC meese.

might want to give this a try:

(credit too TheXMan)

1. In mIRC, goto File, Options then select Local Info underneath Connect. Make sure that mIRC is reporting your routers EXTERNAL IP address. mIRC attempts to obtain your external IP address when you connect to an IRC server. If after you have connected to an IRC server, mIRC does not have your external IP address listed, you need to uncheck Local Host and IP address and manually enter your external IP address You can find your external IP address in your routers configuration webpage.

2. In mIRC, goto File, Options and select Identd underneath Connect. Make sure that "Enable Identd server" is checked.

3. In mIRC, goto File, Options and select Firewall underneath Connect. Make sure that "Firewall support:" is set to "None".

4. In mIRC, goto File, Options and select Options underneath DCC. Change the "DCC Ports:" First to 2070 and Last to 2075.

5. On your router, create a rule to forward TCP port range 2070-2075 to your computer. If your router does not support forwarding a range of ports, you can create an individual rule for each port or you can create a "special application" or "application trigger" rule with a trigger port of 6667. Some older routers like the Di-704 do not seem to require this rule.

6. On your router, create a rule to forward TCP port 113 to your computer. If you prefer, you can also add this port to the application trigger rule. If you want to use application trigger rules, I suggest you first set up static rules and verify everything works and then switch over the application triggers.

7. Restart mIRC and verify that all the changes are in place. I noticed that you have to click "OK" on each option screen for the changes to take effect.

I have tested this configureation with DCC sends/receives/chats and it works perfectly. The ports 2070-2075 should provide for up to 6 simultaneous file transfers. If you need more, change 2075 to 2080 and you should be able to transfer 11 files at a time.

IMPORTANT:
If the person you are trying to transfer files with is also behind a router, they must also configure their IRC client and router or you will have problems. Also, if your computer is in the DMZ on your router, remove it. Having your computer in the DMZ and having rules that forward ports to your computer at the same time has been known to cause problems on some routers.


to be honest i have never been able to send behind my linksys router.

I bought a newer linksys router, and i will give these instructions a try now.

one doubt....

when you say EXTERNAL IP....it´s the WAN ip?? (i´m on cable)

i got LAN ips , those if i understood right some seem to solve anything...

and i got one WAN ip, given to me by the ISP

Is that it??

your external is whatever your isp gives you

[AzKidd69]

boy that's funny.. you follow my link and it gives almost the same instructions as someone else typed out ( but Mine has pics too.. LOL)

[Flyer79]

strange my WAN ip is diferent if i check it on the router or by that site

[Flyer79]

well both work..

i´ve tried my LAN ip my WAN ip and both work on RECEIVING, of course i gotta open the doors i´ve specified...

BUT I STILL CANT SEND

If anyone can do it...pls....POST IT HERE

Thankx

I had the same problem initially, and many others have to it seems. I am using a different router, but its basically all the same principle.

Your first step is to set up port forwarding on your router. I setup forwarding for ports 5050 - 5060. This allows for up to 10 connections at a given time through DCC, if you think you are going to need more, open a wider range of ports.

Next you will need to go into your DCC Options in mIRC. You will see two text boxes that show your "First" and "Last" DCC ports. Change those number from 1024 and 5000 to 5050 and 5060 (or whatever port range corresponds with the configuration you used in the Port Forwarding on your router).

Also, for good messure, in mIRC under Local Info.. clear the Local Host and IP fields of any info. Make sure the "Local Host" box is checked and the "IP Address" box is checked, but hazed out. Also, your "Lookup Method" should be set to server, this will make sure that you are sending the WAN IP rather than the LAN IP of your client machine.

On your Identd screen...make sure that "Enable Identd Server, Show Identd Requests, and Enable Only When Connecting" are all checked.

A common mistake I see people make is in the Firewall screen. This should be left alone, a lot of people think this needs to be enabled and the IP of the router entered. This will surely mess things up.

This should get DCC workin' for ya. One last thing... If you have more than one machine on your LAN running mIRC that you want to be able to use DCC, make sure you select a seperate group of ports for that machine, there should be no overlapping. Ex... 5061 - 5070 and put that group of ports into your router as a seperate Port Forwarding entry.

Good luck!!!
