2 TopicsLTM for load balance DNS queries with real IP addresses
Hello everyone, I’m seeking advice from experts. I’ve configured an LTM to load balance requests across multiple internal DNS servers. However, I’m facing a challenge: the DNS servers need to see the real client IP addresses in the requests, rather than the LTM’s IP. How can I achieve this? Please note that I only have an LTM license. Thank you in advance for your assistance!44Views0likes2CommentsAllow some DNS queries and block the rest
Hello, I want and irule to just allow some DNS queries and block the rest. I was trying with this that blocks some dns request and permit the rest when DNS_REQUEST { switch -glob [string tolower [DNS::question name]] { "*.google.com" - "google.com" { DNS::header rcode NXDOMAIN DNS::return } } } But I can not negate it and make it works in the other way. Any idea how I could do this? Thanks in advanced205Views0likes2Comments
