Firewall Issues

Mudfish Master Server

This section describes about if you're encountering issues for Mudfish Master Server to connect.

Using -O option

• Moves “Mudfish Cloud VPN” menu from Start button.
• Opens the property window of “Mudfish Launcher” icon.
• 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" 

• Changes the command with -O option. For example, looks like below:

  •  "C:\Program Files\Mudfish Cloud VPN\mudrun.exe" -O 

• -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.

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 the 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,
