Can you use astaro with dynamic DSL

dwchan
We are currently using astaro v5 with a static dsl from AT&T. We have 4 static IP and a netopia router. We no longer need the 4 static IP, but for AT&T, either you get 4 static (business class), or single IP that is dynamic. As far as I know, the netopia router is the one that does the connection (pppoe maybe). The username/password is all configure within the dsl router (This is not a dsl modem), and it doesn't have to kick off my the pc/server in the backend like it use to in the old day.

My question is this, can astaro 7.0 setup so that the external NIC can handle dynamic IP ? or what is the best way to do this?

    If you are using DSL, the best way to implement the Astaro Solution (when using the dynamic IP--I'm on Bellsouth at home, now AT&T, and they use PPOE for connection) is to set your DSL Modem / Router to bridged mode, and install a cable from your external Astaro NIC to the DSL modem directly (the Modem is just that now, a Modem) and have the Astaro do the PPOE authentication and act as the router.  Your internal NIC on the Astaro would then go to your internal network (hub / switch, etc.).  Double NATting the external connection (which is what would happen if you kept the DSL Modem / Router acting as a router) is not a good idea, there are some protocols that have issues with that setup.

    would this work for a DSL router, and not model.  The model is "Netopia Model 3346N DSL Ethernet Switch"  So would the Netopia still in charge of making the connection, or would the connection initial by Astaro?

    I went ahead and did the legwork for you (took all of 30 seconds; search is your friend!)... See

    http://www.netopia.com/support/hardware/technotes/CQG_020-002.html

    This tells you what you need to know (the unit can be set to bridge mode, so that you can configure your Astaro as a router).

    Happy to Help

    I am sorry for being a rookie, but still got couple of quick question

    1.  I find the information about setting the netopia to bridge mode.  But i let the astaro making the PPoe connection, is version 7.0 setup so that eth0 are pppoe ready and once it get connected, it know how to get its IP address from the ISP dynamically?

    2.  Since the eth0 IP may varies, base on connection, when I drop and re-connect to my ISP, does it know how to update its routing table, NAT translation, etc, etc

    Hopefully you have two NICs in this device... I would use ETH0 as your internal interface, with ETH1 (or whatever) as your PPOE connection.

    Upon installation and the first login to an ASG 7.x installation, a wizard runs that will allow you to configure PPOE, etc.

    Yes, if the address changes, all affected systems on the ASG are updated automatically.

    Use the wizard, it really makes things easy.  First thing I would recommend, after you install from the ASG 7.004 ISO is to perform an Up2Date to Version 7.005 --- fixes a lot of bugs.
