Uplink Balancing / Multipath: No Fallback

Xavier2
Hi

ASG220, UTM9 (9.106-17) with two WAN-Interfaces
Uplink Balancing:
Interface1: Weight 100 
Interface2: Weight 0
Persistence Timeout: 1min (smallest possible)

Multipath Rule:
All Services from Internal LAN to Internet IPv4 balanced to just Interface2
with persistence by connection.

In normal operation (both interfaces up) all traffic goes through Interface2. Ok.
With Interface2 disabled all traffic goes through Interface1. Fine too. ;-)

But after Interface2 comes up again some traffic doesn't move back to Interface2, i.e. pings continously sent don't move back.
Why that? There's no connection with ICMP that could be persistent!?

Even worse, traffic from UTM's VoIP-Gateway doesn't move back too.

Best regards
Xavier

    Almost all traffic should flow over Interface1 except for some traffic bound explicitly to Interface2.

    I maintain the recommendations in Post #4.  After the rule binding specific traffic to Interface2, bind Any->Any->Any traffic to Interface1.

    Cheers - Bob
