Flow Preferences ICMP

Flow Preferences ICMP

Learned something interesting from support about flow preferences today.  If you are using dual connections for your MX and you setup an internet traffic flow preference it doesn't include ICMP traffic.  Even if you have the protocol set to 'Any'.  ICMP will always go out whatever you have designated as the 'Primary Uplink'.  Caused me a little grief today while troubleshooting so hopefully it can save you a little time.

I just found out for myself.  Rules containing TCP are honored but rules containing Any do not.
Is there another protocol you tested outside of icmp that also gives this problem?

Getting noticed

Thanks very much for posting about this, I just hit exactly this issue. They should really label the UI dropdown UDP & TCP and not 'any'!
