[strongSwan] IPSec route based VPN - VTI interface TX Errors NoRoute

[Tiago Stoco]

Hi Noel,

I did not give up on this yet. The last couple of days were quite busy at work and home.

However, I have managed to draw a diagram on how I believe the site-to-site VPN would work 👇

It is quite obvious how the traffic should flow through the VPN tunnel to allow the subnets to talk to each other.

I have managed to spin up a new VM running pfSence to test a pfSense to Pfsense setup and then I will spin another VM to replicate the example you have shared.

Finally, I will be able to verify if my idea will work and be able to identify where is the anomaly in my current setup.

Wish me luck,

Best Regards.

Tiago

Hello Tiago,

It's more meant as a practical example on how to configure this and to look for anomalies in your setup.

Kind regards
Noel
