Hello,

Just to share a strange behavior I've just got with the last meteobridge build 6.3 with an RPI setup

after having upgraded to the last 6.3 build 2 days ago, I've discovered that the meteobridge's RPI was acting as a DHCP server giving it's own IP@ as a DNS server and Default gateway

the fact my local network was really impacted (no DHCP guard protection here), I've quickly rollback to meteobridge 6.2 and did not took any time to troubleshoot anything.

this is why I'm not fully confident with what I'm arguing here

this is just FYI Boris

what I can say is 2 x laptop was impacted after some hours after this upgrade

Regards

I am rather sure that it does not act as a DHCP server when connected ONLY via WLAN or ONLY via LAN with your network, if you do both in parallel (which is not intended) you might have problems.

When you share your Meteobridge network settings I can have a look.

hello
here are and was the network setting used
https://ibb.co/XZJBRPVG

and yes I confirm it was acting as a DHCP server with this new version and generated a downtime on my local network

current version
Platform: Raspberry Pi 3 Model B Rev 1.2
RAM: 941 MB total, 526 MB free (44% used)
Storage: WD SLC, 14.6 GB total, 11.7 GB free (20% used, 33.4 yrs)
SW Version: Meteobridge 6.2 (Oct 14 2025, build 4128), FW 1.3

cheers

Hi,
I checked with my PRO2 and there is neither a DHCP server process running nor any DHCP server enablement in the settings when I use a static IP address as done in your example setup.

Can you please send content of "/etc/config/dhcp" and output of "ps w" so I can check settings of your RPI.

hello

sure,

but be aware I've downgraded in urgence, so what you see here is with Meteobridge 6.2 (Oct 14 2025, build 4128), FW 1.3

so not the 6.3 which generated the DHCP server issue

here it is

You are right, DHCP on LAN is enabled. Can you please post the "/etc/config/network" file?

sure here it is with Meteobridge 6.2 (Aug 31 2025, build 4101), FW 1.3

# generated by meteobridge for RPI3
# date: 2022-09-26 20:54
#
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config interface 'lan'
option ifname 'eth0'
# option type 'bridge'
option proto 'dhcp'
option hostname 'meteobridge'

most recent versions, should have it fixed.

this is great news
thank you
