[SOLVED] Configuring vlans betwen dsa and swconfig

[dksl]

Hi everyone, i'm trying to configure some vlans between two routers that have a different switch management.

Main router is a linksys mr8300, installing precompiled build of Openwrt 21.02.2 on this router i can see the consuete Network->Switch tab, so i went with the usual configuration. Lately i've noticed that in Network->Interfaces->Devices in the bridge configuration under 'Bridge VLAN filtering' there's the DSA configuration panel, so i'm a little bit confused on which configuration should be used and what to do with the other...

Second router is a netgear r6220 in which i installed a custom build of Openwrt 21.02.2 (starting from the config.seed in the repo). On this router the switch management is done with DSA and the Network->Switch tab is not present (even in the precompiled repo build), so no doubt on this.

On both routers i configured 3 vlans: lan, iot, guest
The problem is that when i ping the main router from the r6220 with guest or iot intarfaces, no response is received (pinging from the lan interface is ok). If i do a ping from the main router to the r6220 everything works ok with all 3 vlans interfaces.

From what i've read on DSA (not so much to be honest), the changes concern only the internal management of the switch, so communication between DSA and swconfig should not be a problem, but but i could be wrong.

Forget it... there was a problem with the firewall configuration...
