  • 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)
