Cisco RV180/RV180W Administration Guide
In the Local Traffic Selection and Remote Traffic Section, enter these settings:
• Local/Remote IP—Select the type of identifier that you want to provide for
the endpoint:
- Any—Specifies that the policy is for traffic from the given end point (local
or remote). Note that selecting Any for both local and remote end points
is not valid.
- Single—Limits the policy to one host. Enter the IP address of the host that
will be part of the VPN in Start IP Address field. Then enter the IP address
in the Start Address field.
- Range—Allows computers within an IP address range to connect to the
VPN. Enter the Start IP Address and End IP Address in the provided fields.
Enter the first IP address of the range in the Start Address field. Enter the
final IP address of the range in the End Address field.
- Subnet—Allows an entire subnet to connect to the VPN. Enter the
network address in the Start IP Address field, and enter the Subnet Mask
in the Subnet Mask field. Enter the subnet's network IP address in the
Start Address field. Enter the subnet mask, such as 255.255.255.0, in the
Subnet Mask field. The field automatically displays a default subnet
address based on the IP address.
IMPORTANT: 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
In the Split DNS section, check the Enable box to allow the Cisco RV180/RV180W
to find the DNS server of the remote router without going through the ISP (Internet).
Otherwise, uncheck the box to disable this feature. If you enable Split DNS, also
enter these settings:
• Domain Name Server 1—Enter a Domain Name server IP address to
resolve the domain that you enter in the Domain Name 1 field.
• Domain Name Server 2—Optionally, enter a Domain Name server IP
address to resolve the domain that you enter in the Domain Name 2 field.
