OBi202 - Any advantage to hooking router to OBi?

(1/3) > >>

mwalt2:
My original thinking when I bought the OBi202 was to connect it to my cable modem and then connect my router to the LAN port of the OBi.  I could not get this to work when I tried (no internet access for router devices), so I just connected the OBi to my router and set things up that way. 

I assume internet didn't work because I left my router as a DCHP server and as a gateway.  Are there any other settings to get it to work (turn on DCHP passthrough and change mode to router)?  Also, is there any advantage to using the OBi202 QoS vs QoS on a router running DDWRT?  Thanks.

The main advantages are having an extra port and QOS.  You already have QOS on your router.  If you don't need the extra port then there aren't any big advantages. 

Using DHCP should be fine.  I have my system set up in this way. 

I set the WAN setting on the OBi202 to DHCP. 
I set the OBi202 operation mode to Router.

I set the WAN setting of my router to Automatic IP (basically DHCP)
I set operation mode to "Enable the DHCP Server"

Thanks for the reply.  I decided to put it between the cable modem and my router.  I put my router in the DMZ of the OBi202.  Now I do not have to worry about forwarding any ports for the OBi or QoS on my router and my network should be separate from the OBi.

I should have got an OBi a long time ago.  It's nice to have a 'home' phone again, e911 service, and a dedicated fax number...all for 80 cents a month.

EDIT for anyone reading this in the future - Enabling DMZ broke the ability to call Anveo 933 and 911 for me.  Turning off DMZ fixes this.

Having issues with calls dropping.  OBI Support has suggested that I carry out the setup to which both of you refer:  cable modem to INTERNET port on the OBI202 and LAN port on OBI202 to router.  When I set this up, reboot modem and router, I can make phone calls but cannot connect to the internet.  I have same configuration parameters as giqcass:

I set the WAN setting on the OBi202 to DHCP. 
I set the OBi202 operation mode to Router.

I set the WAN setting of my router to Automatic IP (basically DHCP)
I set operation mode to "Enable the DHCP Server"

Any insight as to what might be going on or what else I need to change or check in my configuration?

Thanks.

I don't find a good writeup on this. Here is my suggestion to throw out, even though I am not at all sure of the result. I just know that you can change it back if it does not improve things, and we can all learn something in the process. Also, hold back until the more knowledgeable folks have a chance to review things.

I suggest putting the OBi202 into bridge mode as a prospective solution. That way the OBi202 will not be doing NAT, and the router will not be contributing to double NAT.

What I would do to try this:

To put the OBi into bridge mode, on the attached phone dial ***0, 31#, 1,1#,1.
To put it back to router mode dial ***0, 31#, 1,0#,1. (comma means pause and listen)
After entering a string, you could just hang up.

What I hope the user will gain:

http://www.obihai.com/OBiAdminGuide.htm says "Instead of acting as a router, the OBi202 can be set to work as a 3-port switch. One of the ports is internal and is used by the OBi202 CPU only, while the two external ports (labelled as Interent [sic] and LAN) can be connected to other devices. This mode of operation is known as the bridge mode. In this mode, all the router features, such DHCP server, firewall and port forwarding, will not take effect. The QoS policy in this case is hardwired such that the native voice and related traffic will always have highest priority (this behavior is not configurable). Furthermore, accessing the OBi device management web pages from either of the two external ports is always allowed."

So I am looking for the OBi202 to get highest priority for bandwidth and for the external router to do what it does normally for everything else.

What am I thinking might make this work:

I am presuming the OBi in this case will use 192.168.10.1 if you haven't set up a static IP for it. (you could inquire about the IP by dialing ***0, 21#.) Presuming the external router is using a different subnet, then the router would send packets addressed to 192.168.10.1  out of its WAN port, which is connected to the OBi202. So I am hoping that the OBi202 recognizes the number and does not pass the packet on to the modem.

How do incoming packets to the OBi202 get routed? I am hoping that the designers allowed for that. It would depend on the OBi202 intercepting those packets. It would presume that the external router is not using the same port for something else. How could that be prevented? I don't know.

Why don't I try this myself? Right now, my router is integrated with the router, and everything is working fine.
