Ubee Interactive Using the IP Filtering Option
Ubee DDW36C Advanced Wireless Gateway MSO Operations Guide • October 2015 50
6.2 Using the IP Filtering Option
Use the IP Filtering option to filter IP addresses to block Internet traffic to specific
network devices on the LAN. Any host on this list is not accessible to Internet traffic.
You may also filter by the MAC address which does not require setting a static lease.
Refer to Using the MAC Filtering Option on page 51.
To filter IP addresses:
1. Make sure a PC is connected to the DDW36C and both devices are powered on and
functioning.
2. Log in to the DDW36C Web user interface. Refer to Accessing the Web User Interface
Locally on page 14.
3. Click Advanced from the main menu.
4. Click IP Filtering from the left side menu. Field descriptions are listed below the
screen example.
MSN Enables or disables the Microsoft network protocol used for
instant messaging.
SIP Enables or disables the session initiation protocol application
layer gateway (SIP ALG). SIP ALG inspects protocol packets
and formats SIP message headers and SDP body to ensure
proper signaling. Note: Some hosted VoIP services prefer this
function to be performed by their own session border controller
(SBC) and require the SIP ALG to be disabled. Some IP-PBXs
may require SIP ALG enabled.
ICQ Enables or disables the ICQ instant messaging program.
IRC666x Enables or disables the Internet relay chat (IRC) protocol used
for text messaging.
ICQTalk Enables or disables the ICQTalk instant messaging program.
Net2Phone Enables or disables Net2Phone SIP- and PacketCable-based
VoIP.
IRC7000 Enables or disables the Internet relay chat protocol on TCP
port TCP 7000 used for text messaging and group forums.

port 8000 used for text messaging and group forums.
