I tried without, no difference.  In fact, my problem is not related to
iptables at all.  If I start tor with DNSPort set to 53, and set my
nameserver in /etc/resolv.conf to 127.0.0.1, it does not work as well.
(First lookup fails, consequent lookups succeed).

Here's my torrc:

RunAsDaemon 1
Log notice file /tmp/tor/log
DataDirectory /tmp/tor
ClientOnly 1
TransPort 9044
DNSPort 53
SocksPort 0
AutomapHostsOnResolve 1
VirtualAddrNetwork 10.0.0.0/8

This bug is driving me crazy!

Cheers,

Douglas
