Hi Ben,

 

 

One option would be to upgrade to 10.2.x, use the updated v10/11 ProxyPass iRule and modify it to use RESOLV::lookup to resolve the external domain name to an IP address.

Or you could use a shell script called from cron to check if the IP for the external hostname has changed. If it had then use bigpipe to update the pool with the new IP address.

 

 

There's a related enhancement request to support name based load balancing using DNS so that TMM would do this for you. You could open a case with F5 Support to add your request to it. If you do, reference BZ353855.

 

 

Thanks, Aaron
