| Platform | Open Server |

## Symptoms

- After Anti-virus and Anti-Bot blades are disabled, the Security Gateway continues to enforce imported IoC feeds when the IPS is enabled. As a result, the Security Gateway unexpectedly blocks traffic that matches IoC feed entries.
Example debug output from the Security Gateway:  

```
# fw ctl zdebug + drop | grep x.x.x.x
[SIM4]?DROP: dos_deny_list_check_ip: TP IOC External deny list is blocking x.x.x.x;
[SIM4]?pkt_handle_stateless_checks: dropping due to dos_pkt_should_drop(),conn:; 
[SIM4]?do_packet_finish:SIMPKT_IN_DROP vsid=0, conn:<>y.y.y.y,x.x.x.x,0,1>;
```
