DC++ and similar Direct connect clients tutorial
« on: August 03, 2006, 07:33:55 PM »
A mini tutorial of how to open ports for DC++.

First thing you must configure your DC++ client:
Go at the "connection settings" tab of the DC++ ;
there select "firewall with manual port forwarding"

Ports  -> TCP = a single port x (between 1025 and 32000)
          -> UDP = a single port y (between 1025 and 32000)

External/Wan IP = your routers external IP (if you use a normal dsl modem leave it blank)

Know you are ready to configure CPF. Go at the "Network Monitor" panel.
There you should click with the right button of the mouse and choose "Add rule"->"add"
at the new window that appear you should put the following rules:

1. Rule for TCP protocol

Action = Allow
Protocol = TCP
Direction = In
Source IP = Any
Destination IP = your computers internal IP adress (you can also use "Any", if you are using a modem and not a router; by this you won't have to change the IP address every time you connect in internet )
Source port = Any
Destination port = x (same with the TCP port used at DC++)

2. Rule for UDP protocol

Action = Allow
Protocol = UDP
Direction = In
Source IP = Any
Destination IP = your computers internal IP adress (or "Any" )
Source port = Any
Destination port = y (same with the UDP port used at DC++)

Then move this rules up, above the default "block IP in" rule. Now DC++ and similar direct connect clients will connect without any problems. ;D

IMPORTANT
you will have to disable the UPnP option from the program you use if you want this guide to work properly. If you don't disable it you will have NAT problems. ;)

A hint, add that you should update your DC++ program, I got pretty unhappy* not finding the "firewall with manual port forwarding" button since it doesn't exist in old versions. Never thought of my version was old.

Hope this will improve the guide :)

Thank you for your help, but I still have problems with setting up dc++ in Comodo. I´m not able to search in my dc++ and Comodo log shows "DDOS attack (UDP Flood)" any time I try it. If turn off the network monitor, everthing works fine.

Please help. Many thanks.

Yago26

P.S. Emule works fine! TCP UDP In has been setted up!

I have the same problem as Yago, I just can't use search. All the other p2p applications work flawlessly.

For using the search you must disable the feature "Do protocol analysis" ;)

If it does not work try to give a higher rate at the "UDP Flood traffic rate"

« Reply #5 on: October 27, 2006, 09:42:21 AM »
1. Application Monitor
2. Add
3. Search for your StrongDC.exe file
4. Set up the parent regarding what the opener is:
Example1: you open it from quicklaunch/desktop/windows esplorer = C:\WINNT\Explorer.exe; Example2: you open it from Total Commander = C:\totalcmd\TOTALCMD.EXE
5. Now you can play with the settings - read the first post here - or set up an "Allow all activities for this application".

Hello!

For using the search you must disable the feature "Do protocol analysis" ;)

If it does not work try to give a higher rate at the "UDP Flood traffic rate"

I have :
- disabled "Do Protocol Analysis"
- added the corresponding rule (with my port) into "Network Control rules"
- allowed all activities for the application (dcplusplus.exe in my case)
- increased flood control options for TCP and UDP to their maxs

but the search still doesnt work :(

Any other ideas?

Thanks in advance!

Is there any other idea ?

At the moment I cannot test DC++. I will test  it on 10-15 of January and will report back any modifications that need to be done. ;)

i use ldc++

altered applicationcontrole rule -miscallaneous - checked: "skip advanced security checks"
tried to alter the dest ip/port ion the in apllaction rule, but cpf asked a while later if i should accept an incoming connection, i clicked "allow" that was gone.

made also a networkmonitor rule:
  allow tcp/udp In
  source ip= any
  destination - ip of the pc where ldc++ runs
  source port = any
  destination port = 1 port where ldc++ goes through
 
-search works

but i get the ddos attack udp flood error in the log, during the first 25 secs of search 310 packets/247 attackers

Maybe this version of comodo v2.4 :) would create an automatic rule for dc++ and other dc++ clients that would make search+download/upload work without creating mannualy a rule. Excuse my bad language.

I use Apex DC++ 1.0.0B2 http://www.apexdc.net/ together with Comodo personal firewall 2.4

I spent several hours, trying to figure out why search doesn't work. It worked only when I switched it to passive mode in Advanced Apex DC++ settings ("Always use passive mode for search").

But I found the configuration which works for me. I used tutorial http://forums.comodo.com/index.php/topic,6167.msg45504.html#msg45504

Apex DC++ Connections settings:
1. Firewall with manual IP forwarding
2. TCP port x
3. UDP port y (differs from x)
4. External/Wan IP blank
5. Checkbox  "Don't allow hub/UPnP to override" unchecked.
6. Checkbox "Update IP on startup" unchecked.

Comodo firewall settings:
Network monitor rules:
7. Rule for TCP protocol

Action = Allow
Protocol = TCP
Direction = In
Source IP = Any
Destination IP = your computers internal IP adress (you can also use "Any", if you are using a modem and not a router; by this you won't have to change the IP address every time you connect in internet )
Source port = Any
Destination port = x (same with the TCP port used at ApexDC++)

8. Rule for UDP protocol

Action = Allow
Protocol = UDP
Direction = In
Source IP = Any
Destination IP = your computers internal IP adress (or "Any" )
Source port = Any
Destination port = y (same with the UDP port used at ApexDC++)

9. Then move these rules up, above the default "block IP in" rule.

Application monitor:
Application ApexDC.exe

10.TCP or UDP In
Action = Allow
Protocol = TCP or UDP
Direction = In
Source IP = Any
Destination IP = Any
Source port = Any
Destination port = Any

11.TCP or UDP Out
Action = Allow
Protocol = TCP or UDP
Direction = Out
Source IP = Any
Destination IP = Any
Source port = Any
Destination port = Any

12. IMPORTANT. Switch off advanced security checks for ApexDC++ in "Miscellaneous" section of Application rule. Without this change search doesn't work. Firewall blocks search results as UDP flood. Check this in Activity logs.
Checkbox "Skip advanced security checks" is checked.

13.Restart ApexDC++
