Hello
I CVS's current today to an OpenBSD i386 system that I use as a
filtering bridge. The interface to the outside has no IPv4 address assigned
to it. In fact on most OpenBSD filtering bridges you usually don't have an
IP address assigned to an interface that is part of the network you are
filtering.
The bridge is operating properly.
I received the following error:
tethereal: Can't use filter: Couldn't obtain netmask info (dc0: no IPv4
address assigned).
dc0 is operating as part of the bridge as show below:
bridge0: flags=41<UP,RUNNING>
Interfaces:
dc3 flags=7<LEARNING,DISCOVER,BLOCKNONIP>
dc0 flags=7<LEARNING,DISCOVER,BLOCKNONIP>
Here is a listing of interfaces on the system:
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 32972
