GTM answering DNS query with 127.0.0.1 Coveo Test
Hi All,
I got a problem with my GTM, where everytime I do DNS query to mail.google.com from user to GTM, GTM always answer this DNS query with 127.0.0.1. The strange thing is this 127.0.0.1 answer is only appear at some domain under google.com (mail.google.com, translate.google.com). If I do direct nslookup on GTM box from command line, I get the right answer for mail.google.com. But when I do nslookup from user to GTM, the result is 127.0.0.1.
This is a HA BIG-IP box with LTM and GTM module inside. OS that was running is 11.5.3 HF1. This system was deplyoed a month ago, and everything was running well until suddenly it can't answer DNS query to mail.google.com.
Does anybody ever face a problem like this?
Thanks before,
Ahmad
