How to configure Comodo firewall 3 or 4 for emule.

1. Go to : Firewall -> Advanced -> Attack Detection Settings -> Miscellanous and disable  Do Protocol analysis

2. Go to : Firewall -> Advanced -> Predifined Firewall Policies and select Add...

Give a name at the new Predifined Policy for example: Emule

Add the following rules:

Rule 1

Action = Allow
Protocol = TCP
Direction = In
Description = Rule for incoming TCP connections
Source Address = Any
Destination Address = Any
Source port = A port range = (start port = 1025 / end port = 65535)
Destination port = your TCP port of emule

Rule 2

Action = Allow
Protocol = UDP
Direction = In
Description = Rule for incoming UDP connections
Source Address = Any
Destination Address = Any
Source port = A port range = (start port = 1025 / end port = 65535)
Destination port = your UDP port of emule

Rule 3

Action = Allow
Protocol = TCP or UDP
Direction = Out
Description = Rule for outgoing TCP and UDP connections
Source Address = Any
Destination Address = Any
Source port = A port range = (start port = 1025 / end port = 65535)
Destination port = A port range = (start port = 1025 / end port = 65535)

Rule 4

Action = Allow
Protocol = ICMP
Direction = Out
Description = Ping the server (edk network)
Source Address = Any
Destination Address = Any
ICMP Details = ICMP Echo Request

Rule 5

Action = Ask (enable Log as a firewall event if this rule is fired)
Protocol = TCP
Direction = Out
Description = Rule for HTTP requests
Source Address = Any
Destination Address = Any
Source port = A port range = (start port = 1025 / end port = 65535)
Destination port = 80

Rule 6

Action = Block (enable Log as a firewall event if this rule is fired)
Protocol = IP
Direction = In/OUT
Description = Block and Log All Unmatching Requests
Source Address = Any
Destination Address = Any
IP Details = Any

3. Start Emule. When Comodo asks you with a popup, choose Treat this application as select Emule and enable Remember my answer.

Have a nice file sharing. (:WIN)

If you have connectivity problems:
Go at Firewall -> Common Tasks -> Stealth ports wizard and select
Alert me to incoming connections- stealth my ports on a per-case basis
---------------------------
Because of a bug you must change the rule 5 (for HTTP requests) to allow. I hope this will be resolved with the next updates.

Could you please elaborate on why you need to disable protocol analysis? What's the reason? Performance?

Comodo's protocol analysis blockes some packets of the KAD network. Although it does not impact performance, it interfears with the search ability in kad.

They should work with almost all the filesharing programs. (probably limewire will not have any problem with those rules).

Hi Pandlouk

I have followed your decription, but it seems that the search function in emule is not longer working.
I can download the files that are still in the transfer list, but I can´t add new files to the search fearture because I do not get any results.
What´s going wrong?

Regards,
Metamagic

The search in kad should work fine with those rules. Are you talking about the search through the servers?
Try to perform a search and check your cfp log to find out what port/protocol is blocked; if it is the port 80/tcp change the rule #5 from ask to allow; cfp has a bug and the ask rules are treated as blocked.

Hi

I just upgraded from CPF2 to CPF3, so the interface is all very new to me. I followed the above instructions for emule exactly but something is wrong because I'm connecting to servers and kad with a lowID. Disabling the firewall for a moment produced a highID so clearly it's not anything else causing it.

Protocol analysis is off.

Any help much appreciated.
