Question

Hi Everyone,

I have a RUTX09 router on the way. This will be used with a provider which will most likely assign a private IP address behind their CGNAT.

I host servers on my home network and will need to be able to forward ports from outside. Naturally, this means setting up a VPN to a server hosted externally (AWS, Azure etc.)

Is there any significant difference between the performance of OpenVPN or IPSec (IKEv2)? I would prefer to use OpenVPN as the provider's CGNAT issue may cause issues with IPSec.

Thanks and regards,

Joey

Hi,

Perhaps this link could help you to decide:

Hi,

I'm fully aware of that. What I would like to know is whether the ARM processor in the RUTX09 router supports hardware acceleration for either of those VPN protocols.

Thanks,

Hello,

Processor has "crypto engine". Throughput* for IPSEC / OpenVPN can be expected:

- Openvpn AES-128-CBC 25 Mbit/s

- IPSec aes128-sha1-modp1536 85 Mbit/s

*RUTX is still on development.
