Paul, Dave

 

I saw this same behavior when I did lab 2a. Without the zone pair or the
service policy the router was still passing traffic between interfaces. I
was puzzled when I saw this, but wrote it off an moved on. I did have the ip
inspect log drop-pkt turned on and it showed no traffic being dropped . Is
this because it's a bridge interface in zone self and able to pass traffic
between what it considers anything else in zone self? I didn't make note of
the software version and I haven't found any documentation that mentions
that it shouldn't have the zone-pair or service policy.

 

Any insight on this would be appreciated.

 

Thanks

Dave,

I can certainly see your confusion.  However, I think that if you just bind
the zones to the interface it will still permit traffic as you indicated.  I
think you would have to create a zone-pair and quite possibly even add a
service-policy before the default behavior changes to the implicit deny.
Last night, I was working around with communications to the "self" zone and
I found that to be the case.  HTH, and anyone please correct my thinking if
I am incorrect.
