if I would need an additional IPv6 address I'd just add IPV6ADDR_SECONDARIES="ipv6addr" to this file; if I would need an additional IPv4 address this works only by a virtual device e.g. eth0:1 like this:
That's not true, you can add ipv4 address to the interface in the same way:
| IPADDR2=172.17.170.101 | NETMASK2=255.255.255.0
There is no need to create a virtual network device.
ah ok, and the other values?
IPADDR2=192.168.1.10 BROADCAST2=192.168.1.255 <-- NETMASK2=255.255.255.0 NETWORK2=192.168.1.0 <-- GATEWAY2=192.168.1.1 <--
Interesting... With these settings, namely GATEWAY2=..., how the arbitration is done (in networks stack) which of gateways is used for packets to be sent outside of networks the machine is on?
As far as I know FreeBSD, there can be only one gateway (BTW, synonym: default gateway). Theoretically, the machine can have more than one gateway, but for that you need to have specially configured firewall/nat. Is this somehow different in Linux, and Linux does that auto-magically?
Valeri
in case they don't match the first IP address?
Thanks, Walter
