Re: [Zenloadbalancer-support] Unable to run http/https services via L4TxNAT in DNAT mode
Sometimes works and sometimes it does not works. Right now I resetup the Zen LB but the same setup is no longer working in DNAT mode. If I switch it to NAT mode it works. What can be the issue and where should I look for. tcpdump on the real server shows the client ipaddress(172.31.8.15) and the real server ipaddress are connecting to each other.

Hi, you need to isolate the backends in a different subnet than the clients, in other case, the backend will nevet use the default gw to access to the clients. Laura.

Hi Folks, I sincerely would reqeust you to have local DNS server configuration available which can monitor the health of Farm and can detect the failure and route away from failed host. I really think this is much needed configuration since it already has farm guarding available. Let me know if you guys would like to discuss further.

That is really sad :( . But any way lets see if somebody is interested in developing something similar. By the way Bind can be installed on ZLB without any issues right? Wondering if I could write quick bash script with the help of check_* utilities and then update the zone using nsupdate?

Re: [Zenloadbalancer-support] Can ZLB be used at Global Traffic Manager or like 3DNS
Hi Manish, It seem that your case doesn't need any DNS engineering if all of your real servers/hosts is under ZLB. You can simply put example.com DNS record for corresponding VIP.

If you can do it with, let's say, BIND, the ZLB in front of BIND servers can help DNS service scalability. I have experience with a load balancer hardware. The scenario is by putting two DNS servers or two group of DNS servers with different different output ordering. Each DNS server or group of DNS servers is related with one of two VIP. If there is DNS request hit a VIP, so it will be served by DNS server or group of DNS servers which will give ordering priority to IP from related ISP.

Re: [Zenloadbalancer-support] Can ZLB be used at Global Traffic Manager or like 3DNS
Hi Manish, Your example is like my previous case. But, I'm using only one load balance at user site and DNS servers wih different correlated VIP behind the load balancer as my previous description. But, this solution and I believe the F5 3DNS solution will fail too if the client using Internet Explorer or behind the proxy or using DNS cache which disregard TTL of DNS record. For making likely this F5 3DNS solution you just have to put DNS/BIND service on ZLB host and do some scripting with using existing check_* of ZLB for updating DNS zone files.

Re: [Zenloadbalancer-support] Can ZLB be used at Global Traffic Manager or like 3DNS
you mean it will route away the traffic from down host, right? I am more concern about inbound load balancing at ISP level. I mean say I have 2 ISPs terminated on firewall and then next hop is ZLB how this scenario would work? That's why I am talking about GTM which can take care of load balancing of different ISP. Let me draw the diagram and share or do you have that topology ready then please share.
