Step 3 

 Plan Your Configuration 

The EdgeMarc 4562 can be deployed as a gateway router in a network. It can also be deployed 
in a network behind an existing firewall. Based on your deployment criteria, consult the following 
documents for further configuration: 

  EdgeMarc 4500 Series Converged Networking Router Installation Guide 

  VoIP Operating System (VOS) for EdgeMarc User Manual 

Helpful Hints

 

Although not recommended, the 4562 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 4562’s public IP address for the following ports: 
 

Port Type

 

Firewall Ports to Open

 

UDP

 

161 (SNMP) and 162

 

(SNMPTRAP)

 

RTP

 

1056 to 1255

 

TCP

 

SSH TCP 22 for remote management & TCP 80 for WAN 
configuration-downloads

 

Telnet

 

23

 

FTP

 

TCP 21 for stateful TCP-session control from 4500 to Edgewater 
FTP server

 

MGCP

 

2427, 2429, 2432, and 2727

 

NTP 

123 

SIP 

5060 and 5075 

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. 

Please Note:  Traffic shaping for this configuration is only available if the enterprise data 
devices are also installed behind the 4500.
