Categorical protocol filtering
The following are example situations in which the protocol filtering is configured where NAT is disabled:
l
If a subscriber is blocked from only PPPoE and SNMP, then the subscriber retains access to all other
protocols and all ports.
l
If PPPoE, IPv4, and Uplink Broadcast are blocked, and check the All others selection, then only
