The outer WAN VLAN carries the inner VLAN's frames, whose 4B 802.1Q tag counts as payload at this layer. To fit the inner's 1508B baby-jumbo payload plus that tag it needs 1512, not 1508. Harmless before only because the physical `lan` (9000) absorbed the extra bytes; this makes the outer's MTU literally reflect what it transports.
