Routers are bandwidth killers!
Posted: Thu May 11, 2023 7:09 am
I run an OpenVPN server on my TrueNAS system since many years. I never was completly happy of the global performance and decided to check what's going on. The question is, why do I have only 3MB/s when connecting from outside of my house.
The configuration is very easy:
OpenVPN server --> Google Wifi with NAT rule --> Orange ISP Livebox Router with DMZ rule --> 1Gb fiber
Test 1: transfert a file from my Truenas server to my PC --> speed 100MB/s (which is OK for me)
Test 2: transfert same file from OpenVPN client inside the local network --> speed 50MB/s (which is OK regarding the small Server CPU)
Test 3: transfert same file from OpenVPN client connected between Google Wifi and ISP router --> speed 15MB/s (which is small considering there is only a NAT rule to run!)
Test 4: transfert same file from OpenVPN client over 5G network --> speed 3MB/s (which is very poor!!!!!!)
Do you think the result is normal?
Anything I could improve to increase the bandwidth?
It is very annoying to my use now and I search a way to puch up the bandwidth
your comments and experience is very welcome
thanks you all
