A server will never forward queries anywhere unless the client asks for
recursion. Your local clients will do this if they use 10.0.1.7 as
their resolver, but other server that try to use it as an authoritative
server for your domain will send non-recursive queries.

NS records have to point to host *names*, not IPs. So that should be
something like:
away.company.com. IN NS ns.away.company.com.
ns.away.company.com. IN A 10.0.2.7
