I used to work only with openwrt x86, configured zapret + dnscrypt2 dnsmasq, openvpn sever on it, I hardly know Ubuntu. This PC has a built-in network card and 2 pcie cards, wan was configured on one pcie card, it automatically received a static ip, the second one has a cable to the switch and a PC with windows 11, and the internal card went to the router. There was a need to remake this whole system on ubuntu and got stuck at the very beginning. I installed Ubuntu 24.04. 2, the system immediately received the Internet from the provider's cable (enp5s0), but I can't give the Internet to the other connectors (enp6s0 - router and ens4 - switch). I tried to make a connection through netplan on ens4, I registered the static ip of the provider with a difference in the number at the end and the gateway of the provider. As a result, the system writes that there is a connection, and the Windows PC also writes that there is a connection, but there is no Internet. I also can't connect via ssh from a Windows PC, I installed the necessary packages on Ubuntu, I entered 127.0.0.1 in Putty, it asks for a user and password, but no matter what I enter, it always denies access. I gave the root password, but with root, too, access denied

I need an Ubuntu machine for subsequent installation of amnezia VPN server with xray, for connection to the home network from the outside. In my country, the protocol wireguard, shadowsocks, cloak is already blocked, so I will have to switch to x-ray, but unfortunately I did not find information about the possibility of setting up an x-ray server on openwrt. Openwrt was installed on the ssd of this Ubuntu machine, and zapret + dnscrypt2 + openvpn server were configured. I need all this to have access to YouTube, x.com, Facebook (meta). But recently, the openvpn protocol began to be blocked especially strongly, because of which I can no longer access these resources when I am at home. Also, this whole structure is needed so that while at work, I could connect to my home PC on Windows, to edit video and use it as a file network storage. That is, in general, before the bans, I had the following chain: Internet provider -> router -> wifi and switch -> 2 Windows PCs. Then I had to redo it like this: Internet provider -> openwrt x86 (zapret, VPN server, dnscrypt2) -> wifi router and switch -> 2 windows PCs. Now I need to transfer openwrt x86 to Ubuntu to run amnezia VPN x-ray on it, instead of the now non-working openvpn
I forgot to mention that the provider connection is via dhcp, that is, now through the enp5s0 interface I get the Internet with dhcp enabled on auto
