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

    You shouldn't need the weighting, but didn't you write that backwards?

    However, it sounds like you would have been better off putting Interface1 into 'Standby interfaces' instead of using weighting or a multipath rule - have you tried that?

    Cheers - Bob

    Hi Balfson.

    Yes, I tried that and it works but there's traffic from another internal LANs that shall go other Interface1. So standby is no solution.
