The VENDOR access list is correctly configured to permit traffic from the source IP 192.168.32.0/21 to the loopback interface (10.199.100.1) for TCP port 22, within the specified time range (VENDOR_ACCESS). However, the access list (VENDOR) is applied inbound on FastEthernet1/0 but is not applied to the loopback interface (interface loopback 100). To resolve, apply the VENDOR access list to loopback 100: interface loopback 100 ip access-group VENDOR in This ensures that traffic destined for 10.199.100.1 (loopback interface) is correctly filtered and permitted.
