Claim 8:
9. A method of operating a network device, comprising:
providing connections for a plurality of client devices in a local area network using an embedded router (eRouter);
bridging communication between a network and the embedded router using an embedded cable modem (eCM);
providing an eRouter physical interface to execute a generic routing encapsulation (GRE) domain name system (DNS) query from the eRouter to a DNS server to obtain at least one IP address to implement a GRE tunnel;
providing an eCM physical interface to execute a GRE DNS query from the eCM to the DNS server to obtain at least one IP address to implement the GRE tunnel;
storing data in memory; and
executing, by at least one processor, instructions stored on said memory to cause said network device to:
receive selection of the DNS server;
receive selection of the eCM physical interface or the eRouter physical interface;
receive selection of a query type;
transmit the GRE DNS query to the DNS server from the eRouter physical interface and receive the GRE DNS results at the eRouter physical interface when the API receives selection of the eRouter physical interface; and
transmit the GRE DNS query to the DNS server from the eCM physical interface and receive the GRE DNS results at the eCM physical interface when the API receives selection of the eCM physical interface.
