Mudfish Master Server

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

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.

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.

This section describes information if you have a problem to communicate with Mudfish nodes (not master server).

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)

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,
