Cirrususing a URL for node in a pool ?
Hi all,
we have a project to use the LTM as a reverse proxy.
We need to have the LTM virtual server listen and forward to a downstream Virtual server (URL) on another LTM.
So effectibvly a DMZ LTM forwarding to a URL on an APP LTM..
So the question is what is the best way to achieve the result, we would like the DMZ LTM to be DNS aware so it can resolvle the URL in case it changes to the DR site.
My inital thoughts are to build a Virtual server with a FQDN node and static route to that and static to the DR IP address.
is this the way to do it ??

Hi Adrian,
as I learned just yesterday, since TMOS v11.6.0 you can specify a pool member by FQDN now. So a new A record for the specified host will be taken into account.
Thanks, Stephan
adrian_171483ok.. thanks stephan.. i did note the FQN node in the GUI.
I presume that the LTM unit itself needs to resolve the DNS records via the default system settings..
the reason i ask is that our own DNS servers are not available to the LTM at the moment.
- StephanMantheyHi Adrian, I guess it works this way. But haven´t tested it yet. Alternatively you can redirect the client to the fallback server and it will be up to the client to do the name resolution. (Works in all current TMOS versions.) Some related code was discussed here: https://devcentral.f5.com/questions/f5-load-balancing-and-rewrite-header Just change the real server IP addresses and hostname mappings, please. Thanks, Stephan
