I've set up a Linux (Ubuntu 10.04) server with multiple VLANs.
Routing is enabled for all interfaces. The 'eth2' interface is
basically used as a VLAN trunk:
eth2 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:192.168.190.2 Bcast:192.168.190.255 Mask:255.255.255.0
inet6 addr: fe80::210:18ff:fe0a:ac42/64 Scope:Link

eth2.2050 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:192.168.102.1 Bcast:192.168.102.255 Mask:255.255.255.0
inet6 addr: fe80::210:18ff:fe0a:ac42/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:463381 (463.3 KB) TX bytes:730316 (730.3 KB)
The setup appears to work fine. Now, for reasons beyond my control, I
must change the behavior so all outgoing broadcast/multicast packets
are sent untagged (regardless of their source). I'm hoping that this
would be possible with ebtables, but not being very familiar with it
yet I was hoping for some guidance. Is this possible?
Thanks,
-Mike
