Tunnel Monitor with AWS

L1 Bithead

Hello Everyone


Does Tunnel monitor work PA - AWS IPSec ?

I've heard it will not work, only PA - PA Connection


I'd appreciate it if you could help me !

Thanks !

The tunnel monitoring feature itself will work perfectly fine, it's just using ICMP to monitor the given host. While PAN technically considers it to be a "proprietary" feature, it works with any ICMP enabled host regardless of what the tunnel peer is. 

Thank you for reply 🙂

then, I have one question


In this picture, as you can see, tunnel monitor is down now

so can I understand peer is not allow icmp now ?스크린샷 2021-11-22 오후 9.18.59.png


It means that the tunnel IP (used by default with tunnel monitoring) can't send/receive ICMP traffic to the specified tunnel monitoring host. Sometimes you'll see people create a tunnel interface without assigning an IP, but one is required for tunnel monitoring to function. 




1. Make the tunnel interface and tunnel IP

2. Allow ICMP at tunnel interface

3. Config tunnel monitor destination ip(Network -> IPSec Tunnels)


Is it right ?

I'm sorry for bother you ...
