We have launched our WireGuard server.
WireGuard is a new VPN protocol, way faster and simpler than OpenVPN, without sacrificing security.
Our WireGuard server is located in Netherlands and will provide you with a shared IPv4 address and a full /64 IPv6 prefix.
Connections are accepted over UDP port 443. You can't use WireGuard if your ISP blocks UDP.
You can setup up to 3 devices for each VPN account.
We will later add a full documentation and the option to have incoming IPv4 ports (aka “port forward”) or a dedicated IPv4 address.
To start using WireGuard, go to My account > Services: VPN v3 Europe > WireGuard.
Support for PPTP and L2TP/IPsec will be stopped at the end of this month.
While we might not stop the servers right away, users should switch to OpenVPN as soon as possible to avoid any disruption.
We will send an email to affected users (if we have their email address).
TLS 1.0 and 1.1 deprecation
TLS 1.2 (or newer) will soon be required to visit our web sites.
You should not notice any difference, unless your web browser is extremely outdated (and vulnerable to many threats).
We have also added support for TLS 1.3 and HTTP/2.
Information for Android 7.0 and older
Smartphones with Android versions before 7.1.1 will soon start getting certificate errors when visiting sites that have a Let's Encrypt certificate (including the Arethusa web site). This is unrelated to VPN usage.
The solution to this problem is to install and use Firefox Mobile. Firefox Mobile does not rely on the OS for certificates.
The PPTP and L2TP/IPsec servers will be stopped on 2020-11-30.
PPTP has always been insecure. IPsec can be secure in a controlled environment, but not in the context of a public VPN service.
If you are still using PPTP or L2TP/IPsec to connect to our servers, it is time for you to switch to OpenVPN.
v3 logins accepted on v1/v2 OpenVPN servers
All v1 and v2 OpenVPN servers now also accept v3 login/passwords. This will allow us to migrate v1 and v2 accounts to the v3 web site without interrupting the VPN service.
When you generate a new configuration file with the v1/v2 control panel and use it, you will now connect to a new server called the transition server.
OpenVPN 2.3.4 or newer is required for the transition server. The configuration file includes new certificates.
When the v1 and v2 servers are stopped, users on the transition server will be automatically transferred to a v3 server without any interruption of service.
At the moment it redirects to arethusa.su, but in the future it will probably become our main address.
SU is the country code for Soviet Union, a country that no longer exists. .su domains are managed by a Russian organization, with different rules than .ru domains.
Once a piracy haven, Russia has adopted one of the toughest anti-piracy laws in the world, which evolved into a broad censorship system. They also want to censor anything that could be used to evade censorship, including VPN services.
We've had so far no issues with our .su domain, but we prefer to stay safe by preparing this new domain name.
