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.
