dns fwdadd
Add a DNS forwarding entry. The entries in the forwarding list determine which DNS server should
be used for which PC. If an identification cannot be established within the local LAN , the request
is forwarded to another DNS server, on another network (Internet/LAN to LAN connection). The
connection is negotiated within a PPP link.
