VPN server through DDNS on TL-ER605 (configured by Omada OC200)
Hello,
I hope somebody can answer my questions but first, here's a summary of my setup :
- one modem from a belgian service provider.
- TL-ER605 v1 router. WAN port is connected to LAN port of the modem above, connection initiated by PPPoE with credentials provided by the service provider. WAN IP is dynamic.
- switches : TL-SG3452P, TL-SG2016P and TL-SG2008P on the LAN side.
- 5 acces points.
- OC200 controller (v5.14.26.23, firmware : 1.31.3 Build 20240620 Rel.80383)
- OS used for the VPN client side : macOS
Network configuration is not difficult as I have 2 VLAN. One is private for all devices in house and the second one is to allow only internet access to guests over WiFi on a different subnet.
Up to now, I was using the VPN server package on a Synology NAS and a DDNS provided by Synology. Therefore, I can access my network (at least devices on the same subnet) by connecting to this VPN.
Since not so long, I have 2 domain names hosted by OVH (one private and one for my company). I would like to disable the one from Synology and no longer host the VPN on the NAS and configure the ER605 to host the VPN.
What I already tried (but maybe I'm wrong) :
- Settings > Services > Dynamic DNS :
- I configured a Dynamic DNS entry based on one of my OVH subdomain. The problem is that OVH is not listed as service provider. I used the "custom" option but I'm stuck with the update URL as OVH is providing one which does not contain the necessary variables (i.e. [USERNAME], [PASSWORD] and [DOMAIN]). I filled something base on what I gathered on different forums but impossible to copy/paste as it's considered as a link.
When looking at Insights > Dynamic DNS, I have the following error (see printscreen).
- As it was not working, I configured a new DDNS record in my Synology using the credentials from OVH as this service provider is listed in Synology. All is working fine. I assume that the URL is not correct.
- I went back to the OC200 controller and configured successfully a NO-IP DDNS for free for testing.
Then, I tried to configure the VPN part :
- Settings > VPN :
- Created a new VPN policy
- Created a VPN User
On the client side, I configured a new VPN as follow :
L2TP via IPsec
Domain name : the one provided by NO-IP
Login name : user1
Password : password given for user1
Pre-shared key : the one filled in the VPN policy
Option : Send all network traffic over the VPN connection activated
After making this config, the problem I have :
- When trying to connect to the VPN, I'm getting an error that the L2TP server does not respond.
- Should somebody know the right syntax to fill the update URL for OVH service provider, I'm interrested so my WAN IP could be automatically be updated.
Thanks for your help and support.
Regards.
