Hello @StephenLam48 Welcome to the forum. I don't think that you have to put the DX3301 into Bridge mode. Looking at the Tenda Nova information at https://www.tendacn.com/uk/product/mw6.html , it seems you connect the first Nova cube to the DX3301 by an Ethernet cable. This means that you can leave the DX3301 in router…

Hello @bigkenny You're welcome, but I think that I made a mistake. NBG7510 doesn't support VDSL, so it would not be a replacement for you if you need that with your FTTC connection. Maybe DX3301-T0 would be good for you, as it definitely has VDSL, see…

Hello @bigkenny Maybe NBG7510 would be a good replacement for you with your FTTC connection... https://www.zyxel.com/uk/en-gb/products/wifi-router/ax1800-wifi-6-gigabit-router-nbg7510/specifications I don't think that you can restore the backup file as is. Kind regards Tony

Hello @k1s Something else you could try if you wish, is putting the NR7101 into Router mode. You could make it give out a DHCP address in the 192.168.254.0 network with the LAN DHCP pool set so that it starts as 192.168.254.3 You could then give your NR7101 a static IP address of 192.168.254.2 with subnet mask of…

Hello @k1s A router has to work out the next hop for the routing of IP datagrams, by comparing the destination IP address with what is in its routing table, see http://www.cs.cornell.edu/courses/cs4410/2015su/lectures/lec23-routing.html#:~:text=To%20determine%20the%20next%20hop,first%20next%2Dhop%20that%20matches. So I…

Hello @SAI_Mike Welcome to the forum. Looking at the user guide at https://download.zyxel.com/PLA6456/user_guide/PLA6456_V1.00_Ed2.pdf , are you you able to say what colour and state the LEDs are on your PLA6456 plugs? Kind regards, Tony

Hello Adam, Ok. https://youtu.be/tlqU9UjaVOY setup of PPTP VPN on Windows 10 might help you if you need it. I hope that the PPTP ALG helps too. Kind Regards, Tony

Hello Adam @A_J_M Welcome to the forum. I cannot see any reference to VPN in the user guide at https://download.zyxel.com/VMG8825-T50K/user_guide/VMG8825-T50K_V5.13_5.50.pdf So I think that you need to look at the place where your PPTP VPN is set-up, and look for routing set-up there to tell traffic to use the VPN. -…

Hello @k1s I think that it is because your primary LAN router is using your ZTE modem as the next hop for reaching any address on the 192.168.254.0/24 subnet. The tcpdump log seems to be indicating this, because your ZTE modem is asking by ARP what the MAC address of the NR7101 is, so that it can communicate with it. Kind…

Hello @k1s Thanks for your reply. If you want the NR7101 to have a 192.168.254.71 IP address then I think that there does need to be a connection and route between the NR7101 and the ZTE modem. If you don't, then that is up to you. If you add the static route on the NR7101 and it works, then you could have want you want,…

Hello @k1s Ok. The packet traffic says that there is no connection between 192.168.254.1 and 192.168.254.71 Which seems like a routing issue. The ZTE modem is asking using ARP, so the issue might not be there. I wonder if adding a static route on the NR7101 as per section 10.2 of the user guide at…

Hello @k1s Thanks for your post of the tcpdump output. I have also looked at the man page for tcpdump at https://www.tcpdump.org/manpages/tcpdump.1.html Reading the tcpdump output you have posted shows: at 09:32:09.269783 you send an Internet Control Message Protocol (ICMP) echo request datagram to 192.168.254.71, which is…

Hello @k1s For Port Mirroring to work I mean your connectivity A above. Connectivity A is also what I meant for trying a switch without port mirroring. Kind regards, Tony

Hello @k1s If you had set the computer on the switch to an IP address in the same subnet, e.g. 192.168.254.254, then a Ping should have been possible, as it should be a connection on the same layer 2 broadcast domain. - so not sure what else to look for if physical connectivity is present. If you have a more capable…

Hello @k1s You're welcome. You're probably right about what the Remote Management in PassThrough is for. I am guessing a bit, but… maybe if you put an Ethernet switch between your primary router and the PoE injector LAN port then you might be able to connect a computer to such a switch and then talk to the NR7101 using the…
