Multi Outgoing TUN queue full

Xavier_Ferreira

Hello to all

First of all thank you for your time.

I'm new on open vpn and my configurations are based of an example that i found.. but i tried to do all my home work before posting this.

I have ben having this errors..

Wed Apr 08 23:57:54 2020 ClientVPN1/85.247.64.243:60246 MULTI: Outgoing TUN queue full, dropped packet len=52

some times it connects whit no errors and some other times it keeps throwing this errors constantly even tho that the connection works fine.. only in some cases is that the connection works but is very slow

I have searched internet and tried multiple thing but no success.

I started to think if this would be something whit my internet service provider, could it be?

Thank you.

This is an invalid selection.

oh, ok i should use instead -> ifconfig-push 10.10.10.4 255.255.255.0 ?

If i have have multiple clients, i need to have one client-config-dir for each client?

No .. see --topology in the manual.

No .. and your question is ambiguous ..

You can only have one --client-config-dir per server.

You can have as many CCD files as you need, be it one per client or only for one client.

See --client-config-dir in the manual.
