I’m trying to set up an openVPN server on my ASUS RT-AX55 router at my parents home.
The ISP requires VLAN tagging (requires me to enter a particular vlan id for things to work) + PPPoE logging.
The modem/router provided by them faces the internet. My Asus router WAN port connects to the ISP modem/router LAN Port 1.
When I try to register hostname under asus ddns server, I get the following:
I understand that if I'm using two routers, I need to put the ISP modem in bridged mode for my asus router to get public IP.
I tried doing that, and the WAN IP on my asus router homepage changed from 192.168.x.x
to 100.109.x.x
This is still not my public IP.
When the ISP modem is in bridged mode, I had to enable VLAN and specify VLAN ID.
When that was disabled, things were not working out.
What do I do here?
How can I set up DDNS successfully, so I can always know the public IP at my parents home?
