Help setting up Firewall/Network for OpenVPN & VLAN

Televisor · April 9, 2022, 9:14am

Hello OpenWRT expert

Just a quick & dirty question:

I've successfully set up VLANs from OneMarcFifty's Youtube scenario for IOT / Guest / LAN under V21.02 and also exceeded for additional VLAN for Homeoffice.
On top of this configuration I want to to setup OpenVPN Server for only LAN part

What I've done:

Went through the OpenWRT documentation accordingly for:
Setup OpenSSL via No-IP.com DynDNS
Setup OpenVPN

Outcome:

I can get an OpenVPN connection with my client to the server
but of course no Internet or any LAN access

Could you please give me a hint to the right direction? I've read a lot already, seems to be PBR / NETIFD missing?

Is there any sequence in order to set it up right i.e. first setup PBR, then OpenVPN and afterwards my VLAN environment?

Thanks a lot to you for your time spent to help me.

Greetings and stay healthy

OpenVPN needs to be assigned to a firewall zone and enable masquerade.
Regarding policy routing you have 3 options:

mwan3 package
pbr package
a set of rules/routes for each internet connection.
PBR is the easiest, but if you only want to send lan via the tunnel, it might make more sense to use a set of rule/route.

Hi all, Hi @trendy

I'm sorry but I'm still struggling around this and can't get neither OpenVPN nor internet connection with routing running. I've seen meanwhile another thread Setting up a dedicated VPN VLAN - #12 by JDf with similar topic. I've tried to add according documentation https://openwrt.org/docs/guide-user/network/routing/examples/pbr_netifd#route_lan_to_vpn_with_failover_to_wan and also https://openwrt.org/docs/guide-user/services/vpn/openvpn/extras#network_interface but I don't know where to put hands on.

Thanks for your help and below the outputs (part 1/3):

Are you sure that this is correct?
Furthermore lan interface is assigned to table 1 and then you have a rule to lookup table for lan ingress traffic. vpn is assigned to table 2.

Hi @trendy

Wow, that was fast - thanks for your quick reply. I have to admit that I don't have in depth knowledge about routing/tables. So I don't know whether it is correct, but assuming it is not as you seem to doubt. May I ask in another way. I think this configuration is for a pro very easy but unfortunately I'm not that pro. So when I have Vlans and setup OpenVPN according to the main OpenWRT documentation what do I have to add from the extras section? I mean in detail what action is to be done when declaring interface, assigning to a firewall zone (separate or lan zone?), which SW modules should be installed for PBR, race conditions, netifd etc. I have read so much information and dived in try and errors so heavily but can't succeed. I'm so proud that I've managed to create the Vlan working for my home network divided in Lan, IOT, Guest and Homeoffice zones. I only want to be able to have a OpenVPN connction to my Lan devices and there to have access to NAS and Nextcloud server as well as to route the whole internet connection when I'm in Germany (or anywhere else) and want access to my home in Switzerland to run the TV app (geolocation restricted). I will try with a second OpenWRT router to play around so that my main router keeps up and running. It's not that I'm not willing to learn, but it's very time consuming and I have 2 little children, one with autism, which costs nearly my whole energy. That's just for the background why it's so hard for me to proceed in sequence.

Thank you anyway so much.

Regards

I think for starters it is better to use pbr package. It is much easier to configure everything and it can handle the table creation and assignments. Give it a try, after you revert the settings you applied here, and let us know how it goes.
