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 RPC Command Mode via network. Access will
only be allowed via a Local PC or external modem connected to the
RPC's Console 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.
