Firewall Issues - Mudfish Master Server¶
This section describes about if you’re encountering issues for Mudfish Master Server to connect.
Using -O option¶
After clicking “Start” button of Windows, moves to or find “Mudfish Cloud VPN” menu.
Opens the property window of “Mudfish Launcher” icon by clicking the right mouse button on it.
Modify the command which found at “Target(T)” box that as default, the following value is set:
"C:\Program Files\Mudfish Cloud VPN\mudrun.exe"

As result, “Target(T)” would be like below:
-O option turns on a feature using IP and port of old master server.
Using -t option¶
This option is ‘’‘only’‘’ available on v4 version. If you’re using mudfish v3 version, it’s not supported.
At the property window of “Mudfish Launcher” icon, modify the command as follows:
"C:\Program Files\Mudfish Cloud VPN\mudrun.exe" -t
-t option turns on a feature sending a fake HTTP request.
Firewall Issues - Mudfish Nodes¶
This section describes information if you have a problem to communicate with Mudfish nodes (not master server).
Changing Connection Protocol¶
- As default, Mudfish could communicate with Mudfish nodes based on TCP (port 10008) and UDP (port 10008) based. And default is UDP-based.
- If you feel that your connections are blocked by network firewall, you
can change the connection protocol from one to another
- At ‘Setup -> Program’, you can see these options.
- If you’re enabled Expert Mode , you can see more options for
connection protocol. For examples,
- TCP (Port 10008)
- TCP (Port 443)
- TCP (Port 10006)
- UDP (Port 10008)
- UDP (Port 53)
- UDP (Port 10006)
Changing Mac Address¶
Some network firewall blocks based on Mac address of your NIC card. With googling you can find a lot of links about how to change it for example,
