Configuring Reverse Lookup
After both WXA appliances are added to the domain, corresponding Computer Accounts for
WXA appliances, DNS Host name, and PTR records are automatically created on the DC and
DNS servers. For PTR records to be updated, relevant Reverse Lookup Zones must be
configured on the DNS servers. Networks used for Reverse Lookup Zones depend on whether
WFS acceleration is using NAT. If using NAT, the WXA appliance uses the NAT IP for WFS
services and only the X0 subnets are used as networks in Reverse Lookup Zones. If the WXA
appliances are not using NAT, the Reverse Lookup Zone network must also be configured for
WXA subnets on both locations.
To add a PTR record, perform the following steps:
Step 1 Navigate to your DNS on the data center and remote locations.
Step 2 Expand the Reverse Lookup Zones folder.
Step 3 Right-mouse click on the subnet you want to add a new PTR.
Step 4 Select New Pointer (PTR)... in the pop-up menu.
The New Resource Record window appears.
Step 5 Enter the subnet in the Host IP number field.
Step 6 Enter the Host (A) record name in the Host name text field, and then click OK.
Step 7 Verify that the PTR record is created in the Reverse Lookup Zone folder.
