1) Confirm whether you need to forward at all. If you don't need to,
then remove the forwarders entries and that should take care of the
errors in your log.
2) If you *must* use forwarders, look at the part of the config that you
didn't show us, and determine whether there is something there (e.g.
query-source address and/or port, "server" stanza with an inappropriate
TSIG key or EDNS buffer size, etc.) that is causing your packets
destined for 184.108.40.206 to be dropped or rejected, by the target
server or some intermediate device in between.

> Thank you very much. I tried what you suggested and it seems that these two servers work perfectly. In fact, I can simply set my DNS to these two servers and have the internet names resolved without any problem. The only reason I run my own DNS server is to resolve the intranet names.
