SG-1100 - restoring config from Netgate APU device

[jalano]

FYI in case anyone is running into a similar issue - I had to restore my SG-1100 from the USB stick image because I just dropped my old Netgate APU backup image into my SG-1100 and tried to restore it completely.

It turns out that the SG-1100 has some sort of built-in mini switch and VLAN tags that make the 3 ports in the back work. Here's what I ended up doing to restore my config -

• power up the SG-1100 from factory fresh config. Don't go through the wizard - just go to Diagnostics->Backup Restore and make a full XML backup file. Save this as "sg-1100-orig.xml".

• dump your existing APU config to a new file, I call "old.xml"

• copy old.xml to "new.xml".

• remove the following 2 sections from new.xml: "<interfaces>, <vlans>". In my case, <vlans> and <switches> didn't exist.

• copy the <interfaces>, <switches>, and <vlans> from sg-1100-orig.xml

If you are not using 192.168.1.1 as your device's LAN IP, be sure to edit that in <interfaces> to match your old IP.

At this point you should be able to reload the config without hitting "preserve switch configuration".

I actually tried doing it by hitting the "preserve switch configuration" checkbox and it did offer me a page to edit the vlans and interface settings. However, for some reason that did not end up getting saved and on reboot, on the console it basically asked me the same information all over again. However, it did not have any place to input the information that is saved in "<switches>". The other issue I ran into is if I try to edit the VLAN settings after hitting "preserve switch configuration", as soon as I edit the VLAN for the LAN port, my connection to the web interface drops so I can't complete the configuration.

Anyway, I got it all working now so hopefully this helps someone else!
