Unable To Connect To Server With Internet Censorship

[fidividi32]

Hello,

My wireguard with algo deployment seems to work from other countries I tried, but when I try to connect from Iran (a country with terrible state-powered internet censorship) the connect gets activated on wireguard, but no websites can be reached and nothing loads.

Has this to do with deep packet inspection and is there a way to get around this problem as I thought the whole idea is to get over packet inspections as such via a secure tunnel?

I don't have any control from the client side and using the Wireguard client application (unless a config value), so any ideas are welcome..

On WireGuard's Known Limitations page it's mentioned that WireGuard doesn't do anything to avoid Deep Packet Inspection.

seems all UDP packets are being dropped immediately on popular cloud providers (e.g: Digital Ocean).
try to test UDP availability with running nc -lu [port] on the server and connect it from iran nc -u [ip] [port].
if this is the problem you have to find another provider

Thanks for your comment. As this is on Windows, I used PortQuery.. In both cases, where there is a server that I can connect from Iran and one I cannot, the result is the same: UDP port 51820 (unknown service): LISTENING or FILTERED - so not a good identifier unfortunately.
But I agree I think what they do is filter based on different locations/IP ranges/port/etc. etc.. which to me sounds like deep packet inspection. So one provider in one location works, another in the same location MIGHT work, all about try and error which is super annoying...
