The EdgeMarc 250W can be deployed as a gateway router in a network. It can also be
deployed in a network behind an existing firewall.
Note:
When deploying VoIP services, all connected LAN switches or routers must
support full duplex.
Based on your deployment criteria, consult the following documents for further configuration:

Helpful Hints
Although not recommended, the 250W and IP phones can be installed behind an existing
enterprise firewall. In this instance, the firewall will have to be configured to allow access to and
from the 250W's public IP address for the following ports:
Port Type
UDP
RTP
TCP
Telnet
FTP
MGCP
NTP
SIP
IP phones normally point to a local NTP server for their time reference. The NTP port 123
needs to be opened if your network does not have an NTP server.
Note:
Traffic shaping for this configuration is only available if the enterprise data
devices are also installed behind the 250W.
Firewall Ports to Open
161 (SNMP) and 162 (SNMPTRAP)
