Hello, I'm using a FreeBSD machine as a NATBox/router for two small networks. The installed version is FreeBSD 7.1-RELEASE-p13.
My network setup is one ethernet cable connecting to the NATBox, with 3 VLANs (2 of them tagged). The non-tagged VLAN is the "outter" network, and the other two VLANs are the two networks referred above. Here's my network config for IPv4: cloned_interfaces="vlan18 vlan19" ifconfig_em0="inet xxx.xxx.xxx.51 netmask 255.255.255.0" ifconfig_vlan18="inet 10.5.25.254 netmask 255.255.255.0 vlan 18 vlandev em0" ifconfig_vlan19="inet 10.5.24.254 netmask 255.255.255.0 vlan 19 vlandev em0" ifconfig_vlan18_alias0="inet 10.5.25.253 netmask 0xffffffff" defaultrouter="xxx.xxx.xxx.254" vlan18 has a second IP for a jail running a service needed on that network, but it's not part of my problem. All this works fine under IPv4, both the "inside" networks are NATed, and that's it. Now, I'm adding IPv6. The idea is having an IPv6 address on the router, and two /64 networks for each one of the "inside" networks. But I'm having a problem configuring the network interfaces. Although I have no problem on the main interface, I'm not able to attribute both a globally routable IPv6 address and an IPv4 address to the vlan interfaces. This is what I'm trying to do: ipv6_ifconfig_em0="xxx:xxx:xxx:40::460:1 prefixlen 64" ipv6_ifconfig_vlan18="xxx:xxx:xxx:460:: prefixlen 64 vlan 18 vlandev em0" ipv6_ifconfig_vlan19="xxx:xxx:xxx:461:: prefixlen 64 vlan 19 vlandev em0" ipv6_defaultrouter="xxx:xxx:xxx:40::" When I run /etc/rc.d/network_ipv6 restart, among the output I get this: ifconfig: SIOCSETVLAN: Device busy The final result is that em0 gets the correct configuration, but both vlan18 and 19 do not. They both have the IPv4 and an fe80:... IPv6, but not the globally routed 2001:... IPv6. Is this a known bug? Is there a workaround?
