Irule

Is there an irule that will pull up different SSL certs. For instance, if I do not have a wildcard cert can I create a rule and apply it to my VIP so that if traffic is coming in destined for a certain URL then the irule will bring up the correct cert?

 

 

I am a newbie and I appreciate everyones help. I do not want to bug you guys too much.

  • In order to select which cert to present you would need to have access to the HTTP host header in the client request. In order to inspect the HTTP content in a request, you'd need to have already have presented the SSL certificate.

     

     

    In short, you either need to have a separate IP:port available for each unique SSL FQDN or you need a wildcard cert that matches the domain or subdomains of all FQDN's you want the VIP to answer for.

     

     

    So if you have a few sites with the following FQDN's:

     

     

    a.b.c.mydomain.com

     

    x.y.z.mydomain.com

     

     

    You would need a wildcard cert for *.mydomain.com. If a part of the subdomain's matched, you could get a more specific wildcard cert. For example, *.c.mydomain.com would work for these two FQDN's:

     

     

    a.b.c.mydomain.com

     

    x.y.c.mydomain.com

     

     

    Hope this helps,

  • I figured this was the answer. The problem is upper management, their understand is less than mine on these Big-IP machines. I appreciate everyone who has given me guidance here over the past few days and hopefully I have worn my welcome out.
