@Daid, I think this is what we are asking for. handle the WIFI and Eth as you do, separately. But have a toggle on the touch GUI to use DHCP as normal or to use static IP that is manually configured, one for each interface separately (WIFI could be DHCP and Eth could be Static IP, or any other combination). user settings would be, IP Address, Subnet Mask, and Default Gateway.
Thoughts?,
Cheers,
