Just a slight correction - the firmware/software of RED15 is not identical to the RED 10. RED 15 uses an updated software base and also the tunnel protocol is the same as RED 50 (running on UDP port 3410 instead of 3400 as RED 10).
My ASG 220 firmware 9.315-2 does not allow me to deploy a RED 15, only RED 10 or RED 50. Does anyone know what I need to do to setup the RED 15 on my ASG 220?
Ridercup, you need to have UTM Firmware version v9.50010 or above. You can download it from ftp.astaro.com/UTM/v9/up2date/
If you're on v9.315-2, it should be the "u2d-sys-9.315002-350012.tgz.gpg" as the one you want.
You will then need to manually upload/import it to the UTM from the advanced tab of Management>Up2Date and then it will show up as an available firmware update.
Oh and a side note, you don't need to decompress it or unpack it all, just download it then upload the file from your downloads folder straight to the UTM.
Take note, features in 350 are not part of 317 and vice versa.
