I have a similar setup to yours, I don't know about the reverse lookup
issue, it is probably trying to find the canonical name of the host you
The best solution to this problem is to run a local DNS on the LAN which
is authoritive for 192.168.0.0/16 (forward and reverse lookups) and
forwards all other traffic to the DNS of your ISP, with a cache so you get
faster lookups. I use bind to do this, but there are probably better
(simpler) DNS servers capable of this.
Should you want to use bind, the Linux DNS-HOWTO makes interesting
