DMP Network Connections
Q. What prevents me from centrally managing my DMP?
A.
Ask yourself these questions.
Has your DHCP server changed the IP address assignment for your DMP? 
Was your DMP running when its address changed? 
If these statements are true, do not wait for your DMP to restart automatically. Instead, restart it 
manually. Until it is restarted, it cannot be centrally managed.
Q. Can I use a wireless DMP model as an access point for other devices?
A.
No, not in this release. 
Q. Which IP address is active on my DMP when its Ethernet and 802.11 interfaces are both connected?
A.
Ethernet connections take priority over Wi-Fi connections on DMPs where both are active.
Q. Does a DMP 4305G support Wi-Fi?
A.
No.
Q. Does a DMP 4310G support Wi-Fi?
A.
No.
Q. What might prevent my DMP from receiving an IP address on a wireless network?
A.
These are among the possible reasons.
The Broadcast SSID setting must be enabled on your wireless access points. Is it enabled?
You must reconfigure your wireless DMPs whenever you change SSID settings in your WLAN. 
Did you forget to do this?
Some WLAN administrators enforce a security policy that restricts DHCP address assignments 
to known MAC addresses. Does your administrator do this?
Is your WLAN working correctly?
Do any network address translation settings for your DMP differ from NAT behaviors in 
your network?
DMP Use of Logical Ports
Q. Which logical ports on my DMPs should my firewall ever allow?
A.
As of January 2012, these are the only ports that a DMP might ever use.
