Can GTM redirect URL using cname?

Hi

 

We need to access from internal user to internet. and we have GTM as DNS server.

 

Can we create wide-ip name "; and make it resolve CNAME ?

 

so when user want to access this website, they just type into url and enter. then it redirect user to . ?

 

Is this can be done? or it need LTM+irule redirect.

 

Thank you

    It's been a while for me on GTM-only iRules, but I think this will work for you:

    when DNS_REQUEST {
  if { [wideip name] eq "www.easy.com" } {
     cname "www.verylongname.com"
 }
}

    Configuration:

    1). Configure WIP servicedesk.com with A record and CNAME

    2). Irules

    1. when DNS_REQUEST {
    2. if { [wideip name] eq "www.servicedesk.com" } {
    3. cname "www.service-now.com"
    4. }
    5. }
