I've commited ignoring those kind of errors: https://github.com/alexbers/mtprotoproxy/commit/b0cb48f684a9b6a710f7b6ec7668c56b5dbcfbca. It seems you kernel doesn't support this option.

By the way, which kernel version are you use?

[pasha-zzz]

2.6.36.4brcmarm

[alexbers]

The TCP_USER_TIMEOUT option has appeared since Linux 2.6.37 :)

Anyway, it should work now.

All fine, now there is: Unable to connect to 149.154.167.51 443

Overlaps with following blocked subnets: 149.154.160.0/20 - Telegram Messenger Network 149.154.164.0/22 - Telegram Messenger Network 149.154.167.51/32 - Telegram Messenger Network

I think to connect via Tor. Upstream socks proxy isnt supported? Only socksify?

[alexbers]

Upstream socks proxy is not implemented yet, I didn't test with socksify.

I would advise vpn (openvpn or others) or ipv6, they should work. The tor also should work, but it will be slow.

If you don't have Ipv6, you can use teredo-tunnels, is should be by default on windows and available as miredo (https://en.wikipedia.org/wiki/Miredo) in Linux and BSD distributions.
