Found this nice bug when testing

VPN300 V5.35(ABFC.0)ITS-23WK06-r107740

make a routing rule without Connectivity Check enabled say:

incoming ZyWALL

HTTPS

next hop VLAN443

Then make a rule above that with say

incoming VLAN3000

any

next hop GE4

enable Connectivity Check with Disable policy route automatically while Interface link down checked to a IP that you will fail

Wait for the routing rule to go red then remove it and what happens is the rule that was number 2 goes to numbed 1 and it goes red because its Connectivity Check got enabled because of the routing rule you removed.
