I don't think that has a link?
cat ~/.ssh/config
Host router
HostName 192.168.1.1
Port 22
User root
IdentityFile ~/.ssh/id_ed25519
PubkeyAcceptedKeyTypes +ssh-rsa
anyway as I said, only since I added ddns domain
my network is using ADH from my router.
It's not, unless you're actively blocking the Ubuntu hosted DNS server, or similar.
ok... I did not know
You are not using a fully qualified domain name. You’re only using the hostname alone.
ssh james@pop-os.rest.of.your.domain.com
the domain name is from my router, from ddns
Google systemd-resolved.
Please try the fqdn
same
scp root@192.168.1.1:/tmp/backup-*.tar.gz james@pop-os.Ninjanoir78.ddnsfree.com:/media/james/E/openWrt_backup
kex_exchange_identification: read: Connection reset by peer
Connection reset by 169.150.204.52 port 22
scp: Connection closed
Doesn't look like a private IP ?
it is my wireguard ip, but it is worked before with wg
And that's the correct IP for pop-os.Ninjanoir78.ddnsfree.com to resolve to ?
On internet, but on your LAN ?
Are those hosts on the same LAN ?
Something is not adding up. The IPv4 upstream in the screenshot is 24.75.xxxx.yyy. Your ddns account is resolving to 169.150.204.52.
What do you get if you issue google "what's my IP"? Is it the 24.75 IP or the 169.150?
169.150, the wg
Ok... what is the other end of the WG tunnel? Is this a VPS or a home router that you control? Or a commercial VPN service? Or something else?
I use proton VPN, configured on openwrt, basic config
