I just downloaded the Toastman RT-N VPN noUSB build for my RT-N12 B1 router (tomato-K26-1.28.0500.5MIPSR2Toastman-RT-N-VLAN-VPN). I use a Toastman VPN USB build (RT, not RT-N) on my RT-N16 router (v1.28.7498 MIPSR2-Toastman-VLAN-RT K26 USB VPN). However there's no IPv6 support on the RT-N12, while there is on the RT-N16.
Was this feature removed? There are mini builds labeled as having IPv6 support, so this seems unlikely. Is it only in the USB builds? If so, can I use a USB build on the N12 even though it doesn't have USB ports? Thanks.
