Can you give me yet info about LAN address on the routers?

Hi, Can I connect this mini router with a cable to port on an existing router (at 50m distance)? Is this cat.5e or cat.6 cabel?

Other way is to use p2p in Dahua NVR, does not need any port forward or dyn ip service, just that NVR has access to internet. If the unit has p2p service.

In my opinion this is SOHO router and telnet service isn't needed for normal users.

Willaing want to use the MR200 as a modem, that is to have the MR200 establish only the LTE "physical" layer. WAN interface Sorry for my mistake. You want to use your MR200 like a modem and second...

Firstly and more important question, Do you have public IP address from your ISP?
