I hope you can help. My internet provider gives internet over fiber and send it on VLAN 101, so need to setup my router (RUTX10) to receive.
The only way right now I can make it, work is to use the provided Zyxel router in bridge mode, and i found that to be a weird solution when I have a Teltonika.
Some of them uses an IPTV solution on WAN, some of them mentions 802.1Q Tag
My thought was to make
VLAN = 101 and make WAN = tagged, all others = OFF
WAN = DHCP and interface = eth0.101
I tried interface eth1 and eth1.101, at eth1 then it showed me an IP address (100.64.2.163/24) and status = UP for 5-7 seconds, then it went to down again…
The only place I can find something in the guide about tagged VLAN in the WAN guide (RUTX10 WAN - Teltonika Networks Wiki) is under PPPoE protocol
What can I do/try? What am I missing? Is there anyone who have made Fiber internet with Danish provider Hiper work?
Apologies for a late response.
You seem to have configured everything correctly - 101 VLAN tag is applied on the WAN port of the device. Perhaps you could contact your ISP to check if they can see the DHCP requests coming in from their side?
Alternatively, if they cannot help, I will ask you to navigate to System → Maintenance → Troubleshoot page and enable the TCPdump option. Once enabled, select your VLAN interface (if available) or eth1/wan interface. Press Save & Apply. Capture the packets for ~1 minute and then download the file.
Once downloaded, within the archive will be a .pcap file that can be opened using Wireshark. Open it and check if any DHCP packets are being sent either direction and where it is getting stuck. Screenshot can also be attached in the next comment.
