Why are these issues??? Am I the only person that knows how to setup DNS
PTR records for "virtual" servers that go through NAT??
That is how my gateways work, in a 'cluster', behind an LVM, behind NAT.
There are many ways to ensure that the proper DNS information is there for
this type of setup, requires a few more records perhaps (depending on how
you do this), but it works just fine for me :)
So where are the issues with NAT, or virtual servers? The 'other
abominations' i may agree with if I knew to what those were :)
