Cisco RV120W Administration Guide
In the End Address field, enter the last IP address in the range.
If you chose Subnet as the type, enter the Subnet Mask of the network.
Split DNS
Split DNS allows the Cisco RV120W to find the DNS server of the remote router
without going through the ISP (Internet).
To enable split DNS:
Check the Enable box.
In the Domain Name Server 1 field, specify a Domain Name server IP address,
which is used only to resolve the domain configured in the Domain Name 1 field.
In the Domain Name Server 2 field, specify a Domain Name server IP address,
which is used only to resolve the domain configured in the Domain Name 2 field.
In the Domain Name 1 field, specify a domain name, which will be queried only
using the DNS server configured in the Domain Name Server 1 field.
In the Domain Name 2 field, specify a domain name, which will be queried only
using the DNS server configured in the Domain Name Server 2 field.
Make sure that you avoid using overlapping subnets for remote or local traffic
selectors. Using these subnets would require adding static routes on the router and
the hosts to be used.
For example, a combination to avoid would be:
Local Traffic Selector: 192. 1 68. 1 .0/24
Remote Traffic Selector: 192. 1 68.0.0/16
