Hi. I've added a few A records to the DNS manager which point to IPs internal to my VPN. Is there a way to set reverse DNS internal to my network, say by running BIND? Thanks in advance.

Eh, that didn't help at all - try reading the question next time. I've already set up my A entries. I'd like to make it so that when I connect from one machine within my network to another, it will show a REVERSE entry. For example:

Code: box1.domain.tld (5.0.0.1)
box2.domain.tld (5.0.0.2)

Let's say I'm running an IRC server on box2 - I connect a client from box1 - it will give the client an address in the format of Code: nick!ident@5.0.0.1 rather than Code: nick!ident@box1.domain.tld which is what I'm trying to accomplish.

I would say your going to need to run bind or something simular. You need to be able to create reverse pointer records for your internal dns/ip scheme. Which your going to need your own server to be authoritive on for the internal addresses..

Spearson was right regarding linodes rdns page, but unfortunately that only works with linode owned ip public addresses, not internal ones.

Yes, you will need to run your own authorative DNS server for your internal address space, and set all your hosts to use that host as their DNS server.

There's no need to be rude to someone who's trying to help you... For free... Even if they were off the mark.
