Big auth frames to data frames rate?

Post by amikot » Wed Jul 15, 2020 9:14 pm

Hi,

I was trying to find best cathegory for this, but there is no really goodone. Maybe just here.
Thats my case:
After 2 days of using OpenVPN client on my router I found stats are showing huge numbers:

Code: Select all

TUN/TAP read bytes	983858489
TUN/TAP write bytes	2147483647
TCP/UDP read bytes	2147483647
TCP/UDP write bytes	2147483647
Auth read bytes	2147483647
This is of course impossible that I tranferred 2TB of data, however I have 200Mbps broadband, so it is possible that 2TB was transfered somehow, but I guess there were 2TB of auth frames.

VPN throughput actually is very slow, much slower than expected - max 10MBit/s

Here is my configuration of the client (I have no access to the server config):

https://pasteboard.co/JhOIzEI.png

Client config
remote-cert-tls server
remote-random
nobind
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
persist-key
persist-tun
ping-timer-rem
reneg-sec 0
cipher AES-256-GCM
auth SHA512
verb 4
log /tmp/vpn.log


What can cause this issue?

Thanks :)

Actually I think client stats are incorrect. Router showing much less than that. Comparing WAN transfer with measured transfer trough VPN it looks that there is 2GB auth frames per 1GB of data. Is this correct for that cipher?

Your version of openvpn would help ..


Something like this:
viewtopic.php?f=30&t=22603#p68963

but without the server side .. i guess ..
