Yes, it's RFC2983. There it is specified the Uniform and > Pipe model of tunneling, we only support one of those two. I just read it and I can't find any references to TTL. It seems to be only talking about the TOS field. In any case, RFC2401 section 5.1.2 requires that the TTL in the outer header be independent of that in the inner header. So we may even need to change the default setting to comply.
