Airport Extreme and VOIP

FWIW, I'm facing the same dilema. In particular, I'm going to get TimeCapsule but don't want to give up Vonage.

Any success on this? I to have just migrated off of a linksys and am trying to figure out how to move Setup a DMZ for or port forwarding.

Hi,

I just got an Airport Extreme. I plugged my VOIP adapter into one of the three available ethernet slots on the back of the AE, and it works.

I am having a problem though. Any time a call is received or made over VOIP, the AE drops the wireless signal. So if I'm on my laptop or iPhone, the wireless network/SSID simply disappears.

Even my desktop is affected (wired directly to the AE with ethernet cable).

So, VOIP will work fine with the AE in terms of hardware setup, but I guess I'd say you should expect some bugs in terms of performance.

I've found that DMZ is (I think) referred to by AX/TC as "default host". Which you can get to via the manual setup under internet> NAT and check the box "enable default host at:" there you can enter the ip address of what connection you would like to place in the DMZ. If someone has more info on this I'd love to know how accurate this info is... also wondering why Apple doesn't just call it DMZ (hence my hesitance on if this is fully accurate.

Note: whatever host you set as the default above needs to have a "DHCP reservation" set. This is done from the Internet> DHCP, section of Airport Utility

Its all explained here:

bismillah. hi! brzilian, i found the article you recommended to be very useful. i will give it a shot!

but after reading the article, i have a question, too. if NAT on the VOIP (vonage) device causes performance problems, wouldn't it also be a problem on an airport extreme base station (AEBS)?

the AEBS also uses NAT. on my device the setting is found on the tab where the IP addresses are distributed. there are two choices: "DCHP and NAT" or DCHP alone.

so if a person puts the VOIP device behind the AEBS using the instructions in the article, wouldn't he run into a similar NAT-bottleneck on the AEBS? i have read in many places that the AEBS uses a better NAT system than most other consumer devices, so the bottleneck would be less presumably than the one on the VOIP device.

but shouldn't users also switch the AEBS from DCHP and NAT to DCHP alone? i have read so many articles here about NAT trying to figure out why i even need it at all!?

bismillah. i found a dmz/direct host feature on my VOIP/router. i assigned a static ip to the AEBS and made it the DMZ/direct host on my VOIP/router. so now my AEBS network should not be affected by NAT on the VOIP/router, right?

i tried this instead of rearranging hardware because it seemed easier.
