Version 10.2 Issues

I recently upgraded our BIGIP LTM 3400 from v9.3 to v10.2.


Everything seems to work okay with our old configuration file but our servers sitting behind the bigip cannot use the DNS servers on the outside of the network. They can ping the DNS server but cannot use nslookup.



Is there something different about the new version that I may be missing?

  • Hi Mike,



    If you haven't already, you could run tcpdumps on the client and serverside VLAN(s) to see what's happening. If you need help capturing or analyzing the tcpdumps, you can check SOL411 or open a case with F5 Support.
