Appendix A: Configuring the WXA to the Domain Without Using the WXA Management Interface | 157
Configuring Reverse Lookup
After both WXA appliances are added to the domain, corresponding Computer Accounts for
WXA appliances, DNS Host name, and Pointer (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.
