I get the same message. WAN2 is my one and only connection. I suppose it's a kind of inherent, static route...

I don't have any Static Routes defined manually, but "Diagnostics | Routing Table" lists quite a few that the Router has defined by itself.

OK this is weird. I'm using the "Multi NAT" feature with my external IP addresses set in the "WAN IP ALIAS" box.

If WAN 2 is enabled the routing table shows that all of those external IP addresses are "static routed" through WAN 2, even though WAN1 is my main connection. In that condition I cannot access the cameras via their external addresses - maybe because my "open ports" dialogue says that the interface for them is WAN1 ? Why they should be routed through WAN2 I have no idea.

I can get WAN2 to "drop" simply by moving the wifi router to which it is connected out of range of the 2860. When that happens the static routes disappear from the routing table and I can access the cameras on their external IPs !

I think a line to support is called for....

Support have provided me with an RC firmware which appears to have resolved the issue.
