Figure 21.4 VPN server settings — specification of DNS servers
Specify a DNS server which will be used for VPN clients:
• Use WinRoute as DNS server — IP address of a corresponding interface of WinRoute
host will be used as a DNS server for VPN clients (VPN clients will use the DNS for-
warder).
If the DNS Forwarder is already used as a DNS server for local hosts, it is recom-
mended to use it also for VPN clients. The DNS forwarder provides the fastest re-
sponses to client DNS requests and possible collision (inconsistency) of DNS records
will be avoided.
Note: If the DNS forwarder is disabled (refer to chapter
5.3), the option is not avail-
able.
• Use specific DNS servers — primary and secondary DNS servers specified through this
option will be set for VPN clients.
If another DNS server than the DNS forwarder in WinRoute is used in the local net-
work, use this option.
Advanced
Listen on port
The port on which the VPN server listens for incoming connections (both TCP and
UDP protocols are used). The port 4090 is set as default (under usual circumstances
it is not necessary to switch to another port).
