Example 1: Deny access to all hosts except 192.1.1.5:
Security Mask #1: | 255.255.255.255 | Mask #1 Action: | Deny |
Security Mask #2: | 192.1.1.5 | Mask #2 Action: | Permit |
Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants access to 192.1.1.5 only.
Example 2: Allow access only by addresses that begin with 192.
Security Mask #1: | 255.255.255.255 | Mask #1 Action: | Deny |
Security Mask #2: | 192.255.255.255 | Mask #2 Action: | Permit |
Since 255 is a wild card, Mask 1 blocks all IP addresses. Mask 2 then grants access to all addresses that begin with 192.
Example 3: Allow access only by addresses that begin with 192, deny access to 192.1.1.5.
Security Mask #1: 255.255.255.255 | Mask #1 Action: Deny |
Security Mask #2: 192.255.255.255 | Mask #2 Action: Permit |
Security Mask #3: 192.1.1.5 | Mask #3 Action: Deny |
Since 255 is a wild card, Mask 1 blocks all IP addresses. Mask 2 then grants access to all addresses that begin with 192. Finally, Mask 3 specifically blocks access by 192.1.1.5.
Note:
•Mask #5 has priority over the other four masks. If Mask #5 is set to deny access by "255.255.255.255" (all wild cards), you will not be able to access IPS Command Mode via network. Access will only be allowed via a Local PC or external modem connected to the IPS COM Port.
•When using the wild card address "255.255.255.255", make certain that at least one higher priority mask permits access by your IP address.
