Setting Up The Router For Guest Access; Preventing Heavy Data Traffic From Impacting Telephone Calls - Nortel 252 Fundamentals

40 Chapter 5 User Notes
Note: In DHCP Server mode, the BCM50 IP address will be the lowest
address in the pool.
2
Create the appropriate Firewall rules to add BCM50 access.
Go to FIREWALL / Summary, and create two WAN-to-LAN firewall rules:
One rule allowing access from allowed remote computer IP addresses, to the
BCM50 IP address, for service type HTTPS(TCP:443)
One rule allowing access from allowed remote computer IP addresses, to the
BCM50 IP address, for custom port TCP:5989

Setting up the router for guest access

The recommended approach to provide guest access is by creating an IP Alias,
and using static addressing for the corporate equipment, to make it a member of
the defined Alias subnet. Then use firewall rules to restrict access of the guest
equipment. NOTE: if a BCM50 is used, it will also need to be assigned a static IP
address.
1
Go to LAN / IP Alias, and Enable IP Alias 1.
2
Define a subnet for the corporate equipment.
3
Statically assign addresses to the corporate equipment that are within the IP
Alias subnet.
4
Set up LAN / IP to enable DHCP Server, with an address range that will be
used for guest equipment.
5 In the FIREWALL, set up a LAN-to-LAN rule to block traffic between the
guest subnet (DHCP Pool) and the corporate subnet (IP Alias subnet).
Note: If branch tunnels are being used, the policies on these tunnels should
exclude the guest subnet.

Preventing heavy data traffic from impacting telephone calls

To ensure voice quality during heavy data traffic, bandwidth needs to be reserved
for voice traffic.
