Fix my client and server openvpn config files

Hi, I have started a small OpenVPN project (a few OpenVPN servers under Linux (Debian) OS, all with the same config + radius + SQL for accounting). I’d like you to modify my server’s and client’s config file to make it perfect and limit upload/download speed for each user to 15mbit/s. It DOES work now, I can establish a connection and hide behind the VPN, but I want to improve the settings. I will send the config files via private message. I also tried to implement the script from this answer: [login to view URL] but it didnt go smooth, I had following outputs in the logs: RTNETLINK answers: Operation not permitted RTNETLINK answers: Operation not permitted We have an error talking to the kernel, -1 RTNETLINK answers: Operation not permitted We have an error talking to the kernel, -1 RTNETLINK answers: Operation not permitted Illegal "match" Illegal "match As the next step, I planned to grant some privileges to OpenVPN and command TC, but then I decided to hire a freelancer that will fix it for me. so far i have found following warnings in the logs: 1. ######################### TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) TLS Error: TLS handshake failed TLS ERROR: received control packet with stale session-id=0786b657 4b9781a0 2. ######################### MULTI: bad source address from client , packet dropped 3. ######################### tls-crypt unwrap error: bad packet ID (may be a replay): [ #11 / time = (1580422811) -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings tls-crypt unwrap error: packet replay TLS Error: tls-crypt unwrapping failed from [AF_INET6]::ffff:5.113.139.175:14226 TLS ERROR: received control packet with stale session-id=8ff10dfb 450bb683 4. ######################### WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1569', remote='link-mtu 1521' WARNING: 'cipher' is used inconsistently, local='cipher AES-256-CBC', remote='cipher AES-128-GCM' WARNING: 'keysize' is used inconsistently, local='keysize 256', remote='keysize 128' 5. ######################### WARNING: --ifconfig-pool-persist will not work with –duplicate-cn 6. ######################### PID_ERR large diff [65] [SSL-0] [0___0_________0__0____0______________0________________0_00__0000] 0:1455 0:1390 t=1580398464[0] r=[0,64,15,266,1] sl=[17,64,64,528] max-time for a task: 2 days max budget: $100
