GTM Load balance multiports, single Wide IP

Hi,

 

We are trying to Load Balance using GTMs an URL on two different ports, like test.com on port 443 and also for 80, Important:it needs to be a single unique URL [we can't have test1 for 443 and test2 for 80]

 

I have tried a Wide IP, with a pool, the members of that are the VS on port 443 and then the VS on port 80, Will that work? or How would it be the best way to do it?

  • GTM is used to map domain to WIP on GTM. Example: test.com maps to a WIP pool. The WIP pool contains the LTM VIP. The LTM VIP can have 2 Virtual Servers - one for port 443 and another for port 80 with relevant pool and pool members.

     

  • DNS queries don't typically include port information, so I don't think there is an easy way to determine if a DNS client is querying for for a resource on :443 vs a resource on :80, short of having :443 resources in a subdomain, e.g. 'secure-resource.domain.com' vs. 'resource.domain.com'.

     

  • Thanks Rob, we can not brake down the URL, needs to be unique, is the GTM resolving an URL to an IP Address on the VS only? or is it resolving on a IP Address and a port as well?

     

    Is it only resolving on IP Address only, then that's fine because the F5 cant handle that [as it has two VS with same IP addresses but different ports]

     

  • if you configure GTM pool with both HTTP and HTTPS ports, and one of both service fails, the GTM will still answer with this IP address because of the other service UP.

     

    Are you still using HTTP service??? Most of HTTP published services are only for redirect to HTTPS service.

     

    If this is your configuration, define only HTTPS VS in GTM pool.
