I have a dual nic atom based computer I use as a gentoo firewall. It was working fine; however, I did a emerge -uDNv system & emerge -uDNv world update and now my secondary NIC eth1 seems to come up before I can start net.eth1.

If I try to stop net.eth1 is says its not started. If I have a dhcp server it will pick up an address, but I need to assign and address.

Here is an ifconfig right after boot up. I have disabled net.eth1 from coming up at boot time, however, it still appears as below, even though I have eth1 defined in /etc/conf.d/net to get config info so it just ignores this and defaults to dhcp. I use Squid and dnsmasq and this causes other issues. I stopped Squid, dnsmasq and iptables from starting up at boot.

after net.eth1 startup, I get a second eth1 but with a twist, its called eth1:1

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

============================================================
I cannot figure out why the eth1 boots up the way it does, its very puzzling.

Also, I have 2 of these ATOM computers, as a test, I cloned the original install to this second device and updated it first. It worked fine, its on the second device this started. I will swap the hard drives out and see if the issue follows or stays and update. But perhaps someone has seen this before.

What is the output of lspci? Have the drivers for the cards changed?

This was resolved by fixing my /var/lib/iptables/rules_save file. Iptables updated with a change to the stateful config that broke my old rules. Instead of -m state --state, its now -m conntrack --ctatate. The old config caused issues.

Great. Can you change the title to [solved] to help future users searching the forum?
