[Astlinux-devel] Duplicate INT and EXT interfaces

[Michael K. <mic...@ip...>]

Hi Devs

I learned something today. Having the same interface configured on EXT and INT breaks stuff. I realise that the Network Tab pops an error if this is the case but it still writes it in gui.network.conf. So if you click away from the tab and forget about it then when you reboot the system it will be broken.
It all started when I was trying to write a firewall rule and it kept popping a firewall error even though it was fine. So I rebooted the system and then it was quite broken. Luckily I could still get into the system and after doing ‘arno-iptables-firewall force-reload’ I found the error. I'm concerned though that it was without a firewall after the reboot:

# arno-iptables-firewall status
Arno's Iptables Firewall Script v2.0.2-05-astlinux

    pkts      bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
    pkts      bytes target     prot opt in     out     source               destination

Chain POSTROUTING (policy ACCEPT 0 packets, 0 bytes)
    pkts      bytes target     prot opt in     out     source               destination

Is this the case?

Wondering if it is worth saving the previous network config on each save and after popping an error, the previous network config is reinstated and you are notified of this in the error message.
