What does this
mean?
When deploying a 7550 to a Static Business Class customer, there are no
restrictions on wireless use. (Wireless devices can use the Private LAN)
Any customer devices manually provisioned with the assigned LAN Block IP
addresses will use the Public LAN. These devices on the Public LAN will
have unrestricted Internet access, both incoming and outgoing.
Any customer devices requesting an IP address will be assigned addresses
from the Private LAN (via the DHCP server). These devices on the Private
LAN will have unrestricted Internet access in only the outbound direction (to
the Internet). Internet devices trying to initiate a connection to a Private LAN
device will be blocked by network address translation (NAT). – just like
