How Well Does the Linksys EA6350v3 Work With OpenWrt?

I noticed you used the WAN (internet port) as the trunk.

Essentially if I left the WAN port as tagged across two VLANs such as 5 and 10 tagged to the CPU (eth0) and then bridged the interfaces to these VLANs e.g. eth0.5 and eth0.10 that should work right?
