Trying to use DSA on latest snapshot and my ISP requires the following VLAN config:
WAN Connection Type: DHCP (Automatic IP/Dynamic IP/IP over Ethernet)
802.1Q: Enabled
VLAN ID (802.1Q): 10
802.1P (Priority): 0
IP Version: IPv4 or IPv6
MTU Size: 1492 or 1500
NAT: Enabled
I have tried and tried using both the updated LuCI or directly editing the config but I usually have to reset the router anytime I touch any of the lan ports.
On adjusting the wan either i get a non-functional bridge or 'device not found'.
Edit: I just want to make a working connection, I'll worry about additional VLANs afterward
Haven't checked if VLAN 2 is in use by default but it's often a bad idea to reuse it. Did you add the VLANs one by one? Try that, starting with the one your ISP needs.
Configure as much as you can of the Wan configuration as you can in luci.
To get DSA to connect to your ISP you will need to edit the "network" config in /etc/config
Add the following under " config interface 'wan' "
