My 5G sim card/wifi router (ZTE 888) has two ethernet cables connected - one to my main PC and the other to Proxmox miniPC.

Is IP Pool range correct?


Network settings:

Pinging from PC to miniPC also is working fine:

Question - what DNS server I should indicate during installation? 8.8.8.8 or the suggested by default (it was somehow different like 255.255....).

I am lost a little? Please help.

Hi @Adasvejas , welcome to the forum.

Start by reducing your DHCP range so that the PVE IP is not within it. That usually helps with access to non-standard ports.

what DNS server I should indicate during installation
you should use the same one that you have on your windows workstation. You can also use 8.8.8.8 if you want.

HI, actually I had the same problem twice just after fresh install of 8.1 and now 9.1

What I just noted is that ssl certificates have to refreshed, so https would trigger. I did this:
rm /etc/pve/local/pve-ssl.pem
rm /etc/pve/local/pve-ssl.key
systemctl restart pveproxy

and it worked.

Also a strange DNS resolving problem - IP address pings fine, but not with fqdn. And the best solution was to modify /etc/resolv.conf
domain home
search home
nameserver <my-router>

and it worked perfectly.

And also the last problem for trixie was updating packages. I obviously use non-enterprise, so what I did was to remove those enterprise sources:

rm /etc/apt/sources.list.d/ceph.list
rm /etc/apt/sources.list.d/pve-enterprise.sources

and fill default /etc/apt/sources.list file with special cure:

deb http://ftp.pl.debian.org/debian trixie main contrib
deb http://ftp.pl.debian.org/debian trixie-updates main contrib
# security updates
deb http://security.debian.org trixie-security main contrib
deb http://download.proxmox.com/debian/pve trixie pve-no-subscription

That's all now its perfect
