Hi list. Some of the available phones out thera have dual ethernet ports. As we all know using SIP behind NAT could be frustrating. Some vendors sells phones with dual ethernet ports. Are these just incorporating a hub/switch functionality? The reason for my question is that the normal case for a DSL customer is the possibilty to use one MAC adress from their service. With MAC cloning or other functionality this could work out to be a solution. Does anyone of you out there have any experiences in this matter? /t
The polycom phones (ip 500) have a simple switch built in. I say simple because we had an issue were a network device was generating large amounts of traffic to nonexistent mac addresses and the computer behind the phone would not receive some packets. Probably not an issue though as once we got the network device to behave correctly, we haven't had a single problem. --Jason -----Original Message----- From: asterisk-users-admin@lists.digium.com [mailto:asterisk-users-admin@lists.digium.com] On Behalf Of starmail@prybil.se Sent: Monday, February 09, 2004 10:37 AM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] SIP phones with dual ethernet.

However, it does as well support PPPoE in the firmware. I'm not sure what it's meant for and/or how it actually works. I suppose the phone can sit itself right behind an Ethernet DSL modem with this setup, but I'm not sure whether/how it enables a standard PC to work on the other ethernet port. -- Nicolas Bougues Axialys Interactive
The phones I am familiar with have two ports combined as a hub.

What are you trying to accomplish? What is the architecture of the system you are trying to get operational with NAT?

The assumption must be that the users not will be able to handle configuration of their own routers.
