Reboot for udp traffic ?

[swast]

Hello
I have 2 queues in load balancer
And sets that some sort of traffic goes through 1 queue, and another traffic goes through another
(actually voip traffic - udp - i queue, all other traffic - another queue)

What i found - when in Load balancer i chnage list of interfaces to use - change immeditially makes effect for tcp traffic ( when i press apply changes) but it doesnt make any effect for UDP traffic until reboot

So now each time when i change interface for VOIP i have to reboot firewall
Can i avoid reboots in some manner ?
