Does it need to set allow-recursion?

[WebReactor Networks]

According to < 
http://www.isc.org/products/BIND/docs/config/address_list.html > you should
be able to reference your dial-up network(s) with CIDR notation.  Assuming
that your dial-up users are using your dial-up service, then you can allow
their address block like this:

allow-recursion { 192.168.1.0/24; };
