Hello Toastman, I don't know any other way to contact you so hopefully this will get to you, or to someone who can contact you.
I have an E4200, and I'm currently using your tomato-E4200-NVRAM60K-1.28.0500.5MIPSR2Toastman-RT-N-VPN.bin
I believe the VPN builds are the one with ALL the extras, however IPv6 doesn't seem to be in there, and there is no IPv6 builds like the other non-device-specific versions.
Is there a reason for this, would E4200 need a different implementation?
Much thanks!
