How to raise ipv6 proxy server on Centos 6?

Question

CentOS

So, 3proxy is installed correctly, 50 ipv4 proxies have been working for several weeks, everything is ok, but I can’t figure it out with ipv6 due to my incompetence.
The last line of the 3proxy config:

proxy -6 -n -a-p4001 -i91.240.87.190 -e2a01:230:2:6::8a9

, where 91.240.87.190 - server ip address, 2a01:230:2:6::8a9 - purchased ipv6.
Add an interface:
ip -6 addr add a01:230:2:6::8a9/64 dev eth0
Restart 3proxy:
service 3proxy restart
Well, since the server only has a proxy with login-password authorization and nothing else, then:
service iptables stop
Next, specify the proxy server in the PC settings; when I try to connect Google Chrome to any URL, I see a window for entering a login-password, I enter it, but after that any site gives a 502 error.
If similar actions are carried out for ipv4 (except perhaps to create an eth0: 1 interface, otherwise everything is the same), then any resource opens correctly.
Where can be an error?

Answer 1

The problem was not in 3proxy and its config, but in the settings of the OS itself. Added lines to /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0 files according to the topic here . Everything works great.

I read a bunch of tutorials, I couldn't set it up, I set up fastenv.ru/squid-ipv4-ipv6-proxy
using this one. Everything is very detailed and accessible, thanks to the author.
