Hi mabdrasol, it can be done, no problem on using LTM and GTM on the same box. In regards to best practices, I would suggest you create the DNS configuration on your GTM devices, create listener with an IP address different to the current one serving the DNS request. Test extensively via dig/lookups and only when you are sure all is good, you perform the cutover re-pointing the NS records to the GTM’s listeners.

Hi Oscar, thanks for your replay I’m confused here in this implementations as my f5 has below interfaces -self IP (for LTM) -floating IP (for LTM) -HA IP when I try to add GTM and LTM as a servers do I need to add more self IPs for GTM as I cant use same self IP for GTM and LTM. ---

Hi, The selfip belongs to the device itself, it doesn’t matter if you are using LTM or GTM, so, just add the device once, with the non-floating selfip and that’s it. If you have LTM provisioned and you want to discover the Virtual Servers, then enable Virtual Server Discovery ---

if the devices are in HA, add both non-floating self-ips one for each device. But still add only once, so lets say the HA pair has these two devices: -ltm01 -ltm02 then add the HA pair with a name like this: ltm01-02 and use the non-floating self ip for each device. Important point is that even you have two devices, because they are in HA, you just add once. ---

Hello Oscar, thanks for great tips. now I have added -F5 node with two self ips -create listener ip -create pool with existing LTM VS. -create wideip with a record for this pool. -use dig tool to test dns resolving using listening ip from internal lan and resolving worked fine. now I need to use this test from WAN side but I have a confusion here here is my design remote user \>\>WAN\>\>NET Router\>\>FW\>\>F5 DNS\>\>F5 LTM\>\>server how to map VIP private IP to Real IP? listener IP is a private IP do I need to NAT it in internet firewall to real IP? ---

Yeah you have to NAT on the Internet FW. ---

I have nated the listener IP to real IP but when I try to dig from internet it give no response [DNS](https://10.100.0.65/xui/#)  ››  [GSLB : Servers : Server List](https://10.100.0.65/tmui/Control/jspmap/tmui/globallb/server/list.jsp)  ››  Virtual Servers DNS VIP Address :Real IP Translation Address: private IP ---

Hi, can you please, explain to me what you mean? I have same setup HA LTM working as Active/Standby and i will add GTM License to the box. should I login to the active F5 and add Two servers with Self-IP (one for active and for standby)? should I do this step on active and standby F5? should i use the Synck group in GTM? ---

Hey @mabdrasol Were you able to leverage the BIG-IP DNS feature set?
