Example 1: Deny access to all hosts except 192.1.1.5:
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.
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.
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), all IP
Addresses will be blocked, and you will not be able
to access the RPC-4840N Command Mode via
network. Access will only be allowed via the
Console Port or Modem Port.
·
When using the wild card address
"255.255.255.255" to block access by all IP
Addresses, make certain that at least one higher
priority mask permits access by your IP address.
