Hiya,
Upgraded to 23.05.5 last night and have come back this morning to find all devices on my IoT network have no internet connection. The configuration, which was working as of 23.05.3 hours before, appears to no longer work as intended.
Device still get IPs via DHCP but cannot access the internet.
I can't really see any breaking changes to the Linksys MR8300 (unless I'm not looking hard enough).
It's set up using a bridge, a Wi-Fi SSID attached to the bridge and then I have a firewall rule in place which allows output to the lan zone. Accept and forward are set to reject. This was working prior to 23.05.5.
If you would like me to export my interface and firewall configuration please let me know and I can provide it.
Does mobile phone gets internet through this ap?
what happens if you accept all the firewall rules?
what is the output of
ping 1.1.1.1
nslookup duckduckgo.com
?
*the firewall rule should not be used in the second router. as it is being used as bridged. (not NATed)
Can't even ping out, unfortunately. No change even with the rules set to accept.
Regarding the rule, that's quite funny considering the guide I followed was on the OpenWrt wiki.
you mentioned the word 'bridge'.so i am considering you have second router as repeater.
then you should reconfigure the repeater by following it:
https://openwrt.org/docs/guide-user/network/wifi/relay_configuration
No, that is not how my network is configured. This is the primary access point - LAN has no DHCP server running on the OpenWrt device etc, and the router is a MikroTik hEX. That handles DHCP, DNS etc.
However my setup is a bit weird. On the OpenWrt device is a separate bridge interface with the IoT Wi-Fi SSID attached, which runs its own DHCP server. There is a firewall rule in place which allows output from the IoT zone to the LAN zone.
I followed this OpenWrt article and the video linked for extending a guest IoT network. This worked fine on 23.05.3, so I cannot understand why it no longer works. Before you ask, no, even if I roll back to 23.05.3 the configuration is somehow broken.
I will try your suggestion later and try and bend things to work but who knows if it will.
The only real way to understand what is happening is to review the config.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
