In a view of your current config I see several errors. If you have your own dns server that resolves gslbnav.com then you have to configure a delegate subzone resolution sub.gslbnav.com in primary DNS, so the DNS resolutors (ns1 and ns2) for sub.gslbnav.com must be two GSLB farms, in your example 192.168.93.60:53 should be listening the GSLB farm (NS1), you should configure additional GSLB farm for ns2 server. On the hand you will require to configure a service for load balancing 192.168.93.34 and 192.168.50.16 in TCP 8080 port. To sumup: 1. COnfigure the dns resolution for sub.gslbnav.com in your current DNS server and delegate this zone to ns1 and ns2. 2. NS1 and NS2 must be GSLB farms running 3. Configure a new service for backend load balancing 192.168.93.34 and 192.168.50.16 TCP 8080 with Round Robin or Active-Pasive load balancing algortihm.
