Connecting Mudfish in China

As of December 23, 2019, Mudfish program does not work properly in China because GWF blocks public IPs and domains of Mudfish. This article will explain how to bypass this issue. You will need to check the following requirements.

Step 1: Bypass DNS poisoning

If you downloaded the Mudfish v5 version from https://mudfish.net/releases/, you'll need to bypass DNS poisoning first. This is because the Great Wall Firewall blocked domains such as mudfish.net and api.mudfish.net.

Install Machine DNS Client and change your computer's DNS address or use another DNS poisoning bypass method.

Currently, due to GWF block it returns a wrong IP when it resolves the mudfish domains in China. Normally mudfish IP addresses start with 14.64.X.Y.

C: \ Users \ mudfish> nslookup api.mudfish.net
Server: 2.56.168.192.in-addr.arpa
Address: 192.168.0.2
Name: api.mudfish.net.localdomain
Addresses: 31.13.73.23
          31.13.73.23
C: \ Users \ mudfish> ping api.mudfish.net
Ping api.mudfish.net [31.13.73.23] uses 32 byte data:
Control-c

31.13.73.23 is Facebook's IP, which means that GWF sends an incorrect IP in DNS response, and that IP is also blocked in GWF.

Step 2: Using Mudfish v5.0.9 or Later

First check the "Checklist" below to make sure your loach is ready to run.

Check Points

Make sure the following items are set correctly.

Have you checked whether the SMHNR feature is properly turned off?
Did you flush the DNS cache?

Running Mudfish

Please try running Mudfish v5.0.9 or higher. This version contains some code to bypass the issue.

Known Issues

I'm getting MUDEC_00016 or MUDEC_00320 errors.

In that case, please try again after exiting the program completely.
