DNS Ethics wtih Site to Site tunnel

[Tekmazter]

When configuring a site to site tunnel with a remote peer that is not of the same company and you will be accessing hosts on their network, what is the current standard practice for DNS resolution/provisions?

In the past I have always used HOSTS files for this sort of thing. However, recently I was asked by a client to make available a dedicated DNS server which will perform the lookups of hosts living on their network. Is this common practice? I am only talking about 4 different computers needing access to a couple of different servers. I'd hate to now open up an internal DNS server to make queries over a tunnel when a hosts file in this case would still do the trick.

Only a couple of servers? Doesn't seem worthwhile.

Any way, I'd give them the address of my DNS server(s) and they could configure their DNS servers to forward relevant queries to mine.

I agree with you in that for such a limited number of hosts going after an even more limited number of servers, it seems a bit overkill for this process.

Are you aware of any security issues or loopholes providing DNS services over a tunnel may create?
