Hi eben, On GTM all ports are open for now. I have configured 0 for ports. But on LTM I am allowing 5 ports via an iRule.
Also, I did Wireshark capture on GTM listener IP to see the name resolution of wide IP B. I saw their GTM is actually replying with correct IP address (206.221.101.12) but answer in nslookup comes back as IP address of wide IP A (172.x.x.x). The NAT on ISP firewall changing this when GTM reply back to a query but it should not change since DNS is part of the payload and the NAT should have no bearing on this.
It is a bit confusing please, let me know which of my question you did not understand, I will try to explain again.
Thanks for your help.
