Can't connect network with static IP

[miloose]

HI,

I’m using dietpi on an Intel Nuc.

I was using it via DHCP for my IP, I used No-Ip for dyndns and it’s work fine.

But when I try to change to static IP via detpi-config, my nuc can’t access outside network.
So I can’t configure dyndns, can’t use my nextcloud, etc …

On my router, I have activate the dmz to be sure that is not port forwarding problem, but nothing happens.

I want / have to be on static IP because I have to change the dns for my dietpi nuc (torrent download are blocked by my provider).

Someone have an idea ?

Plz deactivate the DMZ, it’s not necessary and can be quite dangerous if you don’t know what you are doing.

@miloose

Someone have an idea ?

Make sure the IP is in the correct range, what are the DHCP and subnet settings in the router?

And can you show the ouput of ip a when you switched to static IP?

Best to show ip a for both STATIC and DHCP

HI,
Thanks to try to help me.

1. Here’s command IP A with DHCP :

root@DietPi:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group defaul                                                                                                         t qlen 1000

2. Here’s IP A command withe static

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet6 ::1/128 scope host noprefixroute
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether f4:4d:30:63:24:26 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.58/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 2a02:8429:807d:c301:f64d:30ff:fe63:2426/64 scope global dynamic mngtmpaddr

    link/ether 00:c2:c6:eb:ea:2e brd ff:ff:ff:ff:ff:ff

3. Here’s a screen capture of subnet settings :
   

   

4. When I try to use No-IP :
   Before applying settings :
   

   

[ INFO ] DietPi-DDNS | Preparing unprivileged DietPi-DDNS UNIX group ...
[  OK  ] DietPi-DDNS | groupmod -p ! dietpi-ddns
[ INFO ] DietPi-DDNS | Preparing unprivileged DietPi-DDNS UNIX user ...
[  OK  ] DietPi-DDNS | usermod -g dietpi-ddns -G  -d /nonexistent -s /usr/sbin/nologin -p ! dietpi-ddns

And the result :

Here’s Static IP config in dietpi-config :

Thanks for your help.

On STATIC, the gateway doesn’t seems to be correct. It’s 192.168.0.1 but I guess it would need to be 192.168.1.1
