*From what I've read elsewhere, the luci-app-openvpn does not work for configuring an openvpn service through luci, you are better using ssh.
*After trying to include the crl.pem file, I contacted Mullvad support and received this response:
Hello
The file is no longer needed since there are no revoked servers with the new certificate.
I have tried many variations on setting up an openvpn service, but most guides do not seem to be current, and even just setting options as specified without worrying about options missing from luci such as comp_lzo, the service fails to ever start.
If anyone has any suggestions for setting up Mullvad to run as a client on OpenWRT without Wireguard, it would be greatly appreciated.
Offtopic:
But since i started this topic, alot have changed .
I gave up doing this myself. Found some vpn providers that do the installation for you instead, but thats on dd-wrt.
But dd-wrt dont seem to support failover any good, you guys told me it works in OpenWRT.
I will try to search for a vpn provider that do remote installations on OpenWRT.
You should collect and analyze the information to come to a solution.
The analysis requires you to understand the network stack specifics.
