Limitation IPsec VPN performance

L3 Networker



I have 2 PA-500 in active-passive mode (Pan-os 6.1.0)

In the model specification PA-500 shows that "IPsec VPN performance" is 50 Mbps.

I want to make an IPSec VPN tunnel with a cloud provider. The speed that gives me supplier for the tunnel is 100 Mpbs guaranteed.

Does this mean that my connection with cloud provider may not exceed 50 Mbps?

Can you clarify a little more what it means "IPsec VPN performance"?


Thank you




I just saw on Cacti graphs that we are reaching with our supplier cloud an output of 80 mbps.


Our line is 80 mbps simétric.

So I can not finish to understand because it brings more performance if it is limited to 50Mbps.


The tunnel is DES encryption.

Can you clarify this?

Thank you

Palo Alto uses small 64k packet size when they put together their datasheet (worst case cenario).

Many competitors use large packets (best case cenario) in their datasheets.

For that reason you often get better performance with Palo than advertised.

By the way DES is not secure to use nowadays.
