Config of Adtran 3120

I am implementing an Adtran 3120 at a customer site.  Once connected  their internet access slows down and the lights on the 3120 flash orange a lot.   The config is below (minus actual ip and password  info).

There may be some static IP's that are causing the conflict with the dynamic ones set on the DHCP MS server. We are working to get them all  dynamic.

  I have the public interface set as DHCP, should I  change that to static ?
 
There is no private DHCP setting needed for the router because they are  using  the 2008 R2 server for DHCP.

All comments are appreciated.   Please comment.

The Public interface needs to be set the way your ISP needs it to be. Usually it will flat out not work if you get that wrong.

Sounds like you have some IP conflicts and or etherloops that will send your error rates through the roof. Use a network scanner like NetScan or Wireshark to see a list of IPs on the network. Multiple devices with one IP is no minor issue.

What used to be in place of the AdTran that was working correctly?

Thanks for your comment.  I used a tool called Angry scanner to scan the ip's . They had an older router that was performing DHCP and other functions but we never had admin access( they had lost the password) so we put a new routher in.

Found that their were IP conflicts because they also had IP set static on many workstations.

Thanks for your comment, I will check out  NetScan and Wireshark too.
