So I'm back to V4.38(AAAA.0) on Zywall 110 after finding this bug in V4.60(AAAA.0)
On the OPT I have Virtual interface for a LAN 192.168.252.1 and OPT gets the WAN IP but as you can see from this capture every now and then it uses the Virtual interface and not the WAN IP on OPT to send a reply.
I also have a routing rule for incoming ZyWALL source OPTIP next hop OPT which fails to help.

To reproduce this issue,
I would like to confirm the test steps from you.
1.Create virtual interface(Lan IP) base on OPT.
2.Ping to 8.8.8.8 from Lan PC, and packet capture on OPT interface.
No not ping from LAN these are pings incoming to OPT using BQM
