w moim przypadku siec 10.10.0.0/24 jest bez dostępu do neta, a co do niceshapera to standardowo masz w configu :
Cytuj:
<download>
    # Section filter(s) for controlled subnet(s)
    match dstip 192.168.0.0/24.
    match dstip 192.168.1.0/24.
i to samo masz w upload, czyli powinno działać ale ja tego nie testowałem, wiec nie wiem jak z wydajnoscia.
