Hi
Thanks for the reply. However I am struggling to get this working.
The RUT240 connects to the mobile service with no apparent error. Firmware is RUT2XX_R_00.01.12
I have the RUT240 WAN port set as LAN, and is connected to the internal LAN, so I can use that port to manage the RUT240 from a browser on a PC.
The LAN port on the RUT240, connected directly (straight cable, showing link up) to the UTM on a spare interface, which is defined as a WAN (ie external).
I have the RUT240 set in Bridge mode, and I have set the correct UTM interface MAC address set in the RUT240
Question:
What should the UTM WAN interface be set to: PPPoE or just DHCP? From what I have read, its DHCP only, however the "Mobile Configuration" page has an option for "Connection Type" PPP - is that between the RUt240 and the carrier?
If I set the UTM interface to DHCP, so assumed that it would pass, using DHCP, the 4G IP address to the UTM, but the WAN on the UTM picks up a LAN derived DHCP assigned IP address which it has acquired via the WAN interface on the RUT240 which is of course connected to the local LAN to manage it.
If I set the UTM to PPPoE, the link is up (no surprise there) but no IP address is assigned on the UTM interface.
SO - problem is that the UTM is not getting the mobile network provided IP address via DHCP provided by the RUT240.
The RUT240 system log shows "Found already running DHCP-server with X.X.X.X gateway - does this cause the RUT240 DHCP service to stop, hence it appears the Mobile assigned IP is not being assigned to the UTM.
If I remove the LAN connection from the RUT240, and leave it connected to the UTM, then the Carrier IP address IS assigned to the UTM using DHCP - GREAT! - but how can I manage the RUT240 without that LAN connected? I dont want to accept remote management for the RUT240 across the WAN.
Thoughts?
