You're bridging in strange/incorrect way. :( It's br0.77 that should have an ip address assigned and the physical devices should have "inet manual" only. >> but I get an error message that ifup tries to configure the VLAN >> interface twice, but the addresses are set. >> >> When I remove the second "iface eth3.77 inet static" line, which >> should be correct according to my understanding of "man interfaces", >> where it is not forbidding to pass multiple "address" directives in a >> stanza, I get an error about unexpected "address" line and the >> addresses are not set. > > Configuring multiple IP addresses on interfaces like that is new in > recent versions of ifupdown.
