Hi Nick you can configure a l4 farm for dns with success and to use some script like check_dns or something more simple like nslookup or host binary call. It will work like a charm
I hope to read experience of others and more level of feedback in the list. Someone want to share the configuration with udp? I'm sure there are people that use it because we developed the udp support after to receive a lot of request Regard 2013/7/2 Nick Furnell <[email protected]> > Hi Emilio > > I just want to see what the feeling is about Load Balancing DNS servers? > This topic was discussed a long time ago (for an older version) before the > L4TxNAT farms were available - has anyone tried this and are there any pros > and cons? > > We have an almost completely virtualised server infrastructure, with only > 2 Physical DC's and 1 Backup server - everything else is inside VMware > (including a 3rd DC).
