Cisco ASA Sensor for monitoring IKEV2 Site to Site VPN tunnels

PRTG Support,

Some of our ASA Site to Site VPN tunnels are configured to use ikev2 for the phase 1, and we noticed that when using the PRTG sensor "SNMP Cisco ASA VPN Traffic", only the ikev1 peer IP Addresses are located and can be selected, the ikev2 peers are not in the list.

Does PRTG supports or have a particular sensor for monitoring ASA Site to Site IPSEC VPNs using ikev2? If not, is there a workaround or any way of making it work?

Thank you in advance!

Hello there,

Currently there are no sensors to monitor IKEv2, it is further explained in this other article Here. But there is a Workaround that you can follow in order to accomplish this.

Thank you for the reply, I decided to write this question because the article referenced is from 2016, so it could have been possible that the sensor was now available. Either way I appreciated the quick response and the confirmation that the workaround is still valid.

I understand your concern, and unfortunately there is still no update on that feature. It seems like the issue is not with PRTG itself but actually with the way IKEV2 behaves, since it returns the internal IP address instead of the correct target address, therefore the PRTG is unable to monitor it. But the workaround should work.
