ChibiOS Free Embedded RTOS

Hi, I cannot access to chibios site when I'm connecting via VPN. Website doesn't load at all. No warning no captchas. I'm okay with captchas. I'm a master of captchas by now : ) For some of us, VPN is essential for a proper internet connection. Git protocol access is always disabled in my university connection, last weekend github was banned nationwide. I can disable my VPN for accessing chibios but its a nuisance that I hope can be addressed. Thank you.

Hi,

Not sure how to fix this, I am able to access the site and forum through my corporate VPN.

Is it the web site or the forum? the forum does have some IP ranges banned because spam.

Hi,

What country are you at? What VPN service are you using? What location for the servers?

I was in China 3 weeks ago and chibios.org and github were still working without VPN. Also using ExpressVPN or shadowsock everything worked. shadowsock is really great if you have access to a VPS like digital ocean / linode / OVH to be able to run your own server.

It was both website and forum.

Interestingly at the moment I can access via VPN. I'm using PIA. I think my IP has changed. I note my IP address next time I have problem.

I got it again. This time I noted the IP address.

blocked: 46.166.188.232

After I disconnected, and re-connected to VPN, I wasn't blocked and my IP was this:

not blocked: 46.166.190.222

I've tried it a couple times to make sure problem is related to that IP address above.

By the way I figured out that I can set gateway address as IP, so that I get the same IP from the VPN everytime I connect.

@utzig I think you misunderstood, I had connection problems when connection with VPN. Chibios site itself isn't blocked in my connection other services are, that's why I have use VPN.

Hi,

That IP is not banned on our side, we ban only forum access anyway. It must be something else.

I think this is what happens:

* using a VPN means that reaching the internet, once inside the VPN, is done through a proxy.
* the intranet accessed through the VPN has at least 2 proxies.
* everyone inside the VPN uses one or more of these proxies.
* somebody using the proxy is infected with malware.
* the actions taken by the malware are seen as originating from the proxy in use.
* the proxy gets blacklisted on some generic blacklist used by the hosting provider.
* whenever one from inside the intranet is assigned the blacklisted proxy, access is blocked.

The solution is to force the proxy to be one that is not (yet?) blacklisted.
