[OpenIndiana-discuss] Configuring an ethernet interface for just Wireshark listening?

[Hans J. Albertsson]

I'd like to configure an ethernet interface in Openindiana 151a7 to be 
used ONLY as a listening interface for wireshark use.

In the old days I did that using ndd, setting stuff like ipforwarding 
off and such.

Not perfect, but I'd still like to use it occasionally.

I'd like to set it up to listen promiscuously but never letting any 
packets reach beyond Wireshark. I e so that noone can use the inteface 
to access the host.

With the current tools I'm just not savvy enough to do it w/o reading up 
on it first.

The if in question is e1000g1, it is connected direct to the other side 
of my NAT router, which talks to e1000g0.

Can such a non-routing, router straddling setup be made to work and be 
safe??
