Problem to connect to outside networks

[dim800vt]

Well I have a problem I have freshly installed an Ubuntu legacy server 20.04 two times and I have problem with the networking, i have update the netplan config with a LAN static IP with the fallowing config file :



the problem is that i can ping from the server to the router (192.168.69.1) and also I can ping from another pc to the server locally, also I can ssh via a local pc to the server but i cant see any other PC from the server and I cant ping to 8.8.8.8 .

I pretty sure that i have done something wrong in the installation because i do not have used to use the legacy Ubuntu version of the installer.
Never than less I am all ears to every suggestion.

For the PCs you "can't see", are they local PCs on 192.168.69.*, or remote PCs?

For some basic debuggung, can you post the output from the command "ip route", and "ip route get 8.8.8.8" please.
Also, do you hae a firewall operating on the server? If so, please post the output of the command "sudo iptables-save -c".

Minimal netplan:

network:
  version: 2
  renderer: networkd
  ethernets:
     ens3:
       addresses:
          - 172.22.22.3/24
       dhcp4: false
       dhcp6: false
       gateway4: 172.22.22.1
       nameservers:
         addresses: [ "172.22.22.80" ]

I've always disabled DHCP and put in an exact renderer to prevent confusion.
Don't forget to

sudo netplan generate
sudo netplan apply --debug

after any changes to the netplan YAML files.
