Question : Network configuration with a Comcast SMS gateway

I have a new client with a hacked together network.  They run a SMS gateway and a dlink wireless router.  They also need a small (4 port) switch to handle all the network connections.  I am having a horrible time trying to work with the SMS gateway and the DLINK router.  I figured I could just run a cable from the SMS to the DLINK and plug my switch into the DLINK router.  Anytime I would plug the switch into the router, it would take the router connection offline to the SMS gateway.  This client also have 3 different vonage phone phones I need to wire in.  I know the fact that the gateway and router are both trying to handle DHCP is tripping me up, however; I'm not sure how this thing needs to be wired and what I need to do to the DLINK wireless router to make it work with the SMS gateway AND my small unmanaged switch.  Can anyone provide me some insight?

thanks,
Ryan

Answer : Network configuration with a Comcast SMS gateway

--I have requirement to put my servers which are housed locally into a remote datacenter.

Typical scenario

--I am thinking of possible wan connection type it will be 100 mbs ethernet private leased line connecting to the datacenter.

Some type of Metro Optical Ethernet will meed your requirements.


--1) As there is no actual routing involved in the remote site. Put a switch out in the remote site. Create a 802.1 q trunk link from my asa to the switch in the remote site.Connecting one end of the 100 mbs to the asa another end to the switch.  Will this work switching over the wan connection? What would be disadvantages doing it this?

Yes this will work, if you go with a MOE type service, you will need to order the circuit with the capability of QinQ (this is needed as most providers are already using dot1q in their infrastructure) service if you plan to trunk the circuit from the data center to your office. I can not think of any disadvantages, only that the design and implementation required to meet your requirements; do you plan to keep these servers in the same subnet as they are now (you will not need to trunk in this case, if you have a switch at the office that has the capability of trunking [802.1q] then you can just connect
the P2P Ethernet link (MOE) to the switchport of the switch and configure it as an access port in the same vlan as the rest of your network), or do you plan to create a new security zone and new subnet between the data center and office (Highly recommended); this will allow you to segment the network [broadcast containment] and add ACLs for your companies security requirements (if any). Depending on how your current infrastructure is configured, you might need additional configurations to accommodate the new changes. What you are asking is completely doable, you just need to ensure you design the environment to be scalable.
