[indiana-discuss] Zone DNS mysteries

[David Abrahams]

I just got through setting up a new zone with a static IP address on my
local subnet.  My dladm show-link looks like:

  LINK        CLASS    MTU    STATE    OVER
  e1000g0     phys     1500   up       --
  e1000g1     phys     1500   up       --
  bond0       aggr     1500   up       e1000g0 e1000g1
  myzone0     vnic     1500   up       bond0

During configuration, I tried twice to give it my ISP's nameservers (not
on my local subnet) and [ Mystery #1: ] each time it rejected the
network (I think it said the nameserver was unreachable).

To get past that step, I tried setting the first nameserver to the
address of a router on my local subnet (which forwards DNS requests to
my ISP's nameservers), and [ mystery #2: ] it worked!

I logged into my zone and [ mystery #3: ] could not traceroute outside
my local subnet.

I deleted my router's address from the zone's /etc/resolv.conf and [
mystery #4: ] traceroute to yahoo.com worked!

Can anyone clear these behaviors up for me?  Thanks...

Baffled-ly y'rs,
