Hi all

I have 5 public IP's.
This is the interfaces file (/etc/network/interfaces):

auto eth2
iface eth2 inet static
address aaa.bb.157.50
network aaa.bb.157.0
netmask 255.255.255.248
post-up route add -net aaa.bb.176.0 netmask 255.255.255.0 dev eth2
post-up route add default gw aaa.bb.176.241 dev eth2

auto eth2:2
iface eth2:2 inet static
address aaa.bb.157.51
netmask 255.255.255.248

auto eth2:3
iface eth2:3 inet static
address aaa.bb.157.52
netmask 255.255.255.248

auto eth2:4
iface eth2:4 inet static
address aaa.bb.157.53
netmask 255.255.255.248

auto eth2:5
iface eth2:5 inet static
address aaa.bb.157.54
netmask 255.255.255.248

All when firewall has restarted, the main IP is aaa.bb.157.51, but ours
main IP on DNS zone is aaa.bb.157.50.
So, to fix this issue, I log in on firewall and run this command:

service network restart

So, the main IP back to aaa.bb.157.50

This is a hard way to fix the problem, as you can see!
Is there a better way to priorize IP aaa.bb.157.50 to be always main
IP ???

Thanks for any help

Regards
