Rented a VPS to install VPN and proxies.
OS: Debian 9. As the UFW firewall installed.
OpenVPN uses port XXXX. Respectively prescribed ufw allow XXXX. However, when you enable ufw - not boot websites (the connection occurs). Procs also works.
When ufw is disabled everything works as it should.
Please tell me that I am in the settings nedokrutil? There may be some other port needed? Now open 3 ports: SSH, OpenVPN for XXXX and YYYY for proxies.
