Hi all, I am after a bit of help setting up my WAG54GP2 - this was previously connected to VFX but is now fully unlocked. I am currently running trixbox v2.6.0.7 and the WAG has firmware version 2.01.06.

Initially I followed tony's guide myasterisk setup and other simililar guides on the net as it appears that the WAG and really just an adls modem with a PAP2 shoved inside - however I could see no registration attempts from the WAG on my trixbox (watching the asterisk CLI in debug mode) and it would report as registration failed in the WAG status page.

Following on I found that I could turn on debug mode on the router which sends messages to my pc. With this enabled and tshark on my trixbox here are some following observations. Any insight would be most appreciated.

External IP:
TShark: No matter what I do I have yet to see any registration attempts with tshark from the WAG

Debug log from WAG: What really worries me here is when the voip portal reloads this is what is spit out from the device

System started:, reboot reason:C4
subnet mask:
gateway ip:

However my router/gateway is actually, where could 15 be coming from?

Here is a registration attempt according to the WAG's debug log

Via: SIP/2.0/UDP;branch=z9hG4bK-afd8cffc
From: test ;tag=5e444d4bda0ad1c8o0
To: test
Max-Forwards: 70
Contact: test ;expires=30
User-Agent: Linksys/WAG54G-P2-2.01.06
Content-Length: 0
Supported: x-sipura, replaces

Here is a registration attempt from my softphone

Via: SIP/2.0/UDP;branch=z9hG4bK-d87543-0561dc40b84cfb4e-1--d87543-;rport
Max-Forwards: 70
To: "test"
From: "test";tag=b424fc69
Expires: 3600
User-Agent: X-Lite release 1011s stamp 41150
Content-Length: 0

So the WAG's registration attempt seems correct, (except for using my external ip) however it never reaches trixbox - i suspect because of the gateway issues as noted above.

To get around this I tried setting the proxy setting in my WAG as my external ip, now I was getting 404 not found replies, however as best as I can tell it is actually the WAG talking sending responses back to itself, in any case definitly wasn't my trixbox

I have a sinking feeling this device is only going to allow connection on the WAN port and won't connect on the LAN ports... anybody have any suggestions or does anyone have an external trixbox I can connect to

Isn't your Linksys a NAT router? You could switch it to bridge mode and put your asterix in a DMZ, see if that works but I dont think so. might need to reconfigure the linksys to use a local soft-switch. Its odd for your ISP to use a C-class ip for their access router but thats the external gateway, not your routers internal address. Cant you just install a local POTS card into your asterix box or buy an ethernet POTS "converter" also available from linksys?

The more VoIP systems you have there, the more critical battery backup will become to keep a stable service. Might have to simply join an ISP service like the linksys is designed to do, they should be getting cheaper now with more competition.

Time to find a new industry!

I already have voip with VFX, thats the point - the router used to be used for their voip service, now I want it to do VFX -> trixbox -> WAG54GP2. I could buy another ip -> POTS converter but that just seems a waste.

Bridge mode might work - i could even set my asterisk box to be - however then I would have no internet and thus no VFX so that doesn't really pan out for me.

I don't think that is their gateway, the router (not the voice section) reports in the config pages that its gateway is
