Question

I try to separate home use and work use in the following way: incoming fiber connects to a sagemcom router and distributes internet for home use. I want the RUT240 WAN port to connect to the sagemcom router and take highspeed internet from there, and have the SIM card as backup for the work use. I want the systems to be entirely separated. I fail to have RUT240 to accept incoming internet from the sagemcom router, it instead runs failover SIM card driven internet.

RUT 240 runs RUT2XX_R_00.01.14.5

set IP to 192.168.5.1, all connected entities are in the 192.168.5.x space

Sagemcom is 192.168.1.1 and all connected entities are in the 192.168.1.x space

Answer 1

Hi,

my suggestions:

1. do you have a public IP address on your
Sagemcom? If not - get one.

2. if your public IP address is static -> good
Otherwise you need some dynamic DNS service

3. define the RUT240 as DMZ host in the Sagemcom
Alternatively you may also open up needed
port forwards only (if you want that).

And: update your RUT240 to at least firmware RUT2 R 00.07.03.4

Hth,
