To stop the confusion I have attached the entire NAT section of the 2.2.5 config that I backed up (I also have a status_output.tgz file from the 2.2.5 box if you want me to share that with you). Hopefully this will shed some more light on this issue since the order of the NAT section is:
1. Outbound NAT
2. 1:1 NAT
3. Port Forward
4. NPt
These are the steps I took originally but have not been able to reproduce this issue since then.
1. Backup the configuration on a 2.2.5 machine, with RRD data, without packages
2. Shutdown the machine
3. Install 2.3-ALPHA image on a new machine
4. Assign a temp IP to LAN interface
5. Skip the Wizard
6. Restore the configuration, with all areas selected (default)
7. I was prompted to fix the interface assignments, since the 2.2.5 box was not the same as the 2.3 box. So I fixed the assignments, PPPoE and VLAN settings.
8. Checked the NAT section, all the tabs are empty, even after a reboot.
Thanks,
Robbert
