Hello, we have recently added a Point-to_point T1 to an office accross the street. The sites are tied together by ADTRAN TSU's. We use Procurve POE L2/L3 switches and sonicwall firewalls. When service provider came in to provision VOIP phone system (Mitel) they created VLAN-22 (192.168.22.0) on the main site, and accross the street they created VLAN-22 (192.168.23.0). I have not seen this before and was wondering if it's a best practice, or is there a better way to go? We are seeing packet drops on the sonicwalls like from 0.0.0.0 with a mac address of one of the adtrans. Also the outside addresses (not on either subnet) somehow seem to be showing up in the sonicwall logs as an IPSPOOF (obvious because not on local subnet). So why would the connections between the TSU's show up on the local subnets..
Thanks, any pointers would be appreciated. The voice circuits seem to work ok beteen buildings but overall the PTPT1 seems slow. Would like to shake all the errors out anyway.
Thanks in advance.
