Settings Specific to WAN Partners

If you use the DNS Proxy function, X3200 can save previously resolved names
and IP addresses in the cache and on receipt of a request first checks if the de-
sired address can be answered from the cache. This keeps the costs of setting
up WAN connections to name servers outside the LAN at a low level and opti-
mizes performance in the LAN, as requests to frequently used addresses or ad-
dresses already resolved are answered by X3200 itself. How to configure the
DNS Proxy function is described in chapter 6.3.2, page 229 .
When you enter a WAN partner in X3200 , you can define whether X3200 sends
or answers requests for WINS or DNS IP addresses.
