4.
Is a WAN partner selected as default interface?
In this case, the associated DNS are asked. If the connection to the WAN
partner is not active, an attempt is made to set it up.
–
If a DNS can resolve the name, the information is forwarded and a
dynamic entry created in the cache.
–
If none of the DNS asked can resolve the name or no default interface
has been selected, see 5.
5.
Is overwriting the global name server addresses admissible (Overwrite
Global Nameserver =
yes)?
In this case, a connection is set up to the first WAN partner, which is
configured so that addresses of DNS can be sent – provided this has not
previously been attempted. If name server negotiation is successful, these
are entered as global name servers and are therefore available for further
requests.
6.
Request is answered with server error.
