Irule F5 response IP public

Hi,

You could use this irule:

when DNS_RESPONSE {
     set rrs [DNS::answer]
     foreach rr $rrs {
     if { ([DNS::rdata $rr] eq "a.a.a.a")} {
    DNS::answer clear
    DNS::answer insert [DNS::rr "aaa.aaa.com. IN A b.b.b.b"]
 
}
     elseif { ([DNS::rdata $rr] eq "c.c.c.c")} {
    DNS::answer clear
    DNS::answer insert [DNS::rr "ccc.ccc.com. IN A d.d.d.d"]
}
 
}
}

add it to the DNS Listener.

This Irule fixes 2 A records.

a.a.a.a = internal ip address#1

aaa.aaa.com. = the A record#1

b.b.b.b = external ip address#1

c.c.c.c = internal ip address#2

ccc.ccc.com. = the A record#2

d.d.d.d = external ip address#2

Cheers,
