setup-ipsec-vpn VS OpenVPN

I can't connect to VPN. I have run VPN on this Raspberry Pi via IPsec. All of a sudden it stopped working. I tried installing IPsec on another Raspberry Pi, with no success, the same problem. I can't connect.

I have set up a vpn server using this, https://github.com/hwdsl2/setup-ipsec-vpn. I am able to log into the server and shut it down if I chose.

ok so here is the deal... I am currently running this script on a rpi at home that also runs a pihole... I do this for 24/7 ad blocking on my phone and to get around blocks on public wifi...

First, go here and use this setup https://github.com/hwdsl2/setup-ipsec-vpn . I put this on a raspberry pi and it works great, but you can put this on an old laptop or really anything.

you can run your own vpn node on some cheap vps server using algo (https://github.com/trailofbits/algo) or this: https://github.com/hwdsl2/setup-ipsec-vpn

How you connect to your modem will depend on the device you are using, but for windows laptops as an example you download the OpenVPN program and input your modem details there, much like you would any other vpn service. I think there would be some guides on youtube. https://openvpn.net/

I just started playing with CloudConnexa for remotely managing my second pFSense. Really nice and is free for up to 3 concurrent users. https://openvpn.net. Can also self-host OpenVPN access server with a free 2 concurrent license.

If anyone is being blocked check out free OpenVPN

It is likely an issue with the 'cipher' options, if any, that are in your ".opvn" file. This is telling you that the opvn setting is not finding a matching cipher it is allowed to use. The fix per the message would be to add the Servers cipher to your options. https://github.com/OpenVPN/openvpn-gui/issues/381 https://github.com/OpenVPN/openvpn/blob/master/doc/man-sections/cipher-negotiation.rst

I too haven't used the client-nat directive in some years (I currently implement 1:1 NAT with pfsense to access my network because I'm too lazy to change the networks subnet from the default) so I decided to retest and it does appear that OpenVPN Connect clients do not properly support the client-nat directive but the traditional OpenVPN server/clients still do. I've just tested this on OpenVPN 2.6.3 Server, OpenVPN 2.6.1 GUI for Windows from openvpn.net, and OpenVPN Connect iOS 3.3.3 and only the OpenVPN Connect client has any difficulty. Difficulty being that you can use client-nat successfully but it has to be configured server-side it can't be pushed to or setup on the client (OpenVPN Connect) side. The Server and Windows (non-OpenVPN Connect) clients work an any setup whether it's configured server-side, pushed to the client, or set up in the client config.

OpenVPN is a VPN client that I used primarily for work. We used VPN to connect to the dev server and we are using VPN. I also sometimes used that to open websites that got blocked in Indonesia like Reddit.

I connect all the servers with secure OpenVPN private network. And block unused ports anywhere with ufw.

Ensure remote access is by VPN only like the site-to-site with Ubiquitis gear, WireGuard or OpenVPN and there could be a paid option I just don't know.
