翻牆去國內

I have two Raspberry Pi, one in my home abroad and one in China.

My home abroad has a IP V4 address (even though dynamic, hasn't changed since 5 years), home in China has only a IP V6 address. I can ssh to my Pi abroad from home in China.

I have setup a proxy server in China, then forward the port 3128 to my home abroad Pi. So I can view CCTV sports programs even from abroad.

I could have setup a VPN, but a simple proxy is enough for my needs.
