Iran blocks servers after reaching a certain amount of traffic from one client

[johnWinchester01]

Hello
I have been using outline on Irancell and Rightell operators in Iran with no problem but IR-MCI blocks the IP agter it reaches a certain amount of traffic. We had a server only for testing purposes and every key had a 500MB data limit we were almost at a 1TB usage and it was fine with all operators but when we added keys with a higher data limit suddenly IR-MCI blocked our IP!
any Idea how can we solve this problem?

Thanks for reaching out. Rotating IPs may help avoid this, from what we've heard from other server managers supporting users in Iran. Additionally, are you using the prefix feature when you generate your access keys? Curious to see if that makes harder to detect the traffic.

unfortunatly we are still getting blocked even using prefix feature. it would've been nice to be able to use a CDN provider and reverse proxy like cloudflare with outline but cloudflare does not support shadowsocks protocol..any workarounds?

@johnWinchester01 IP rotation would be a better approach than CDN. CDNs are significantly more expensive, and traffic costs are usually a limiting factor for how many users a service can help. It's also harder to set up.

the reason for choosing CDN for us is that our server's ip would be proxied by the CDN provider which is an Iranian service so the government won't block it cuz lots of services depend on it another problem with rotating IPs is that you may get a blocked IP address a lot because a lot of IP ranges have been blacklisted by the government by probing or other means of detecting shadowsocks servers. happened to me couple of days ago, I installed outline and i used aboout 1Gb and the very next day my IP was blocked and i wasn't able to connect to my server with puttyor anything else.

CDN is a must for Iran since it's very difficult to find vps ips that haven't been blocked.
I have 5 servers and can't connect to any of them directly.
