Irule for reverse DNS lookup
Hello ,
Currently we have applied Irule for DNS lookup & allowing DNS entries that only ends with a a particular fqdn
for e.g
when DNS_REQUEST { set fqdn [DNS::question name]
if { !($fqdn ends_with "xxx.org.in")} {
log localo. "----[DNS::question name] Dropped-----"
drop
}
}
Now the issue we are facing is when we try to resolve ip address lfor any particular url that ends with this mentioned fqdn ..we are able to resolve a record i.e ip address
But when we try to resolve hostname.fqdn for particular IP address we are not able to resolve the same.We need to make changes in this Irule for reverse dns lookup. Kindly help me to modify it.
Regards
