Can someone help me with the following problem. I'm trying to get my DC++ working, without succes so far. The following information I achieved at the DC++ FAQ


Active mode requires both TCP and UDP access on the same port for DC++ to work properly

-First you need to set up the router to forward the connections to the computer with DC++. This is could be called Port mapping, port redirecting, port forwarding or something like that.

- You need to forward one port (select a number between 1024 - 65535, they should mostly all be free. The default port is 1412, but it is wise to select a unique one) and make sure both UDP and TCP is forwarded.

- The IP that you are forwarding to should be the internal IP address of your DC++ computer. It usually begins with "192.168", "172.16." or "10.x.".

- When you have mapped a port, you need to open up DC++ and go to the settings. Where you select active mode, in the port field, enter the port number that you are forwarding on the router.
In the IP field, you need to enter the external IP address of your router. This can easily be checked on here. Sometimes your IP address changes, if you have a dynamic IP, when you disconnect from your internet connection. Check your IP every now and then to make sure. It should now be working. If it is working for a while, but the next time you use DC++, you only get "Connection TimeoutĘs or no results when searching, your IP is likely to have changed.


ISA: 192.168.0.1
Workstation with DC++: 192.168.0.2

What I did do is allow port 5555 TCP (inbound & outbound & r&S & S&R). I also created 2 server publishing rules for DC++ TCP inbound & DC++ S&R that are forwarding to my Workstation.

I configured as described above DC++ active to use port 5555 with my external IP. I also tried to use the internal ISA IP but both aren't working.

When I configure ISA to allow all TCP trafic in all directions DC++ is working. Can someone tell me what I'm doing wrong ??

Hi

I managed to connect to the hubs and talk to other users, but the download gets allways "connection timeout". That far I went using the ideas from http://www.isaserver.org/pages/article.asp?id=1080.
From what I know, the outbound port for DC++ is 411 (?). If you have anything new, please e-mail me, because I did almost anything I could think of

OK... Here is what I did as I am running DC++ on my ISA server. I am not sure HOW secure this is but it is the only way I have been able to get it to work.

I configure 3 Packet Filters. They are as follows:

1.) Name: DC++ TCP 411
Type: Custom
IP Protocol: TCP
Direction: Both
Local Port: Fixed Port
Local Port Number: 411
Remote Port: ALL PORTS
Filter Applies to (Local): Default IP Address
Filter Applies to (Remote): All Remote Computers

2.) Name: DC++ UDP 411
Type: Custom
IP Protocol: TCP
Direction: Both
Local Port: Fixed Port
Local Port Number: 411
Remote Port: ALL PORTS
Filter Applies to (Local): Default IP Address
Filter Applies to (Remote): All Remote Computers

3.) Name: DC++ Alternate Ports
Type: Custom
IP Protocol: TCP
Direction: Inbound
Local Port: Dynamic
Remote Port: Fixed Port
Remote Port Number: 411
Filter Applies to (Local): Default IP Address
Filter Applies to (Remote): All Remote Computers

I hope this helps you guys out !

Should this be UDP for protocol, direction Receive only?

Also, is this DC running on the same box as ISA? We would love to get this running so any help would be greatly appreciated. Thanks!

Hi

Have got this working. Basically create both outgoing and incoming protocol definitions for the port you wish to use for DC++ (as configured in active mode - pointing to external ip address). Then create a publishing rule for the internal protocol definitions. Works ok - although connections are abit slow to connect at first.

Sorry guys... looks like I was fooled... seems that my set up does not work as stated. Therefore I am STILL trying to get this to work. As for Ady's suggestion ... well... it does not work in my configuration as DC++ gives me an error saying that the port I am trying to use is already being used by something else.

Oh well... back to the drawing board !

Hi guys I think I have partial answer for you!

choose a port you want to use, for example 5500
Enter that port in DC++

Make protocol defenitions:
DC++ port 5500 UDP
DC++ Port 5500 TCP
DC++ Port 410-413 TCP & UDP

In access policy--> protocol rules
make sure to create a protocol for port dc++ 410-413
go to server publishing rules
Add DC++ port 5500 UDP & DC++ Port 5500 TCP

with this config I can connect activly and download, also search but only passive users can download from me

right ive set this thing up, dunno if ive made ISA slightly insecure but what works and ive tested it fully now is ....

ISA Server = 192.168.0.1
DC++ Machine = 192.168.0.16

Create new access rule

allow from 192.168.0.16
Primary Connection
port : 410-413 TCP Outbound
port : 410-413 UDP Send/Recieve
Secondary Connection
port : 410-413 TCP Inbound
port : 410-413 UDP Recieve/Send

I setup DC++ to use port 2078, so after this mapping i created a server publishing rule with

allow reciever 192.168.0.16
Primary Connection
port : 2078 TCP Inbound
port : 2078 UDP Recieve/Send
Secondary Connection
port : 2078 TCP Outbound
port : 2078 UDP Send/Recieve

You could probably removing some of those mappings as I did each way to ensure it worked first time.

If you fiddle around with it you could probably remove some of them to make it more secure, but at least it works fully [Smile]

Have fun
