Remote DNS
Servers
When the OfficeConnect Remote 840's DNS Proxy cannot find a domain
name in its local static entries, it will forward the request to one or two
remote servers. The remote DNS Server can be learned dynamically if the
remote site is configured for PPP, otherwise it must be specified. Up to
two servers may be specified per domain name.
