Since ‘Core-Update 200’ (currently running Core-Update 202), I observe randomly (in a timeframe of half a day to 3 days at most) failures of the blue network, i.e. i can:
- not reach any device on blue from ipfire (e.g. the Wifi access point)
- but still can ping the blue network interface IP adress.
- all devices on the Wifi network can communicate with each other, but cannot reach ipfire itself or devices on green or red (internet)
Unfortunatley I cannot find any error in the System logs (no DHCP or DNS:unbound issue shown)
There are as well no memory problems (used memory about 5%, goes up to 40% with new DNS Firewall enabled) observed so far.
IPS and IP adress blocklist are enabled.
restart of services (DHCP and/or DNS) did not help, but after a reboot the issue is gone again for a while, so I gues it is not the AP itself.
Any suggestions what (and how) I can check ?
Could it be an issue of the amount of network traffic from/to the blue network (a lot of shelly devices, 3 iPhones and a linux laptop) ?
