RB951G + Huawei E3372 - default routing problem

Hi,
I have RB951G (OS 6.15 also tested on 6.25) and Huawei E3372. Almost everything works fine except one thing. I cannot set to no “add-default-route”. When I use older modem (ppp-out) everything is ok but on this one (lte) I can’t do anything with this option. No matter is it “no” or “yes” it’s always “yes”.
Can You help me?

you need to change the add-default-route settings for the dhcp-client.

So simple, works fine. Great thanks for quick help.

Can You tell me what for is checkbox “add default route” in interface lte ?

Regards

It is for some modems that uses directly the lte interface without the dhcp-client.

Thanks again.
Regards
