Hi all,

I really, REALLY, hope this thread doesn't go stale. I've had bad luck in other networking forums where I got not even one reply. So, all my hopes are on you guys!

I hope my problem seems interesting and poses a interesting challenge to the experienced members of this forum.

OK, so...

I currently have an ISP in Singapore who provides me with Internet and Phone service. Both services are delivered via optical fiber, I have a 1Gb bandwidth (company pays!) and one singe phone line. It is all connected the following way (I explain the abbreviations below):


TP-----ONT-----RG-----CMS-----WR
----------------------|
------------------Phone


And what I am looking at having is something like this:

TP-----ONT-----CMS-----WR----WIred and Wireless PCs
------------------------|
-----------------------RG-----Phone

TP = Fiber Termination Point
Simple fiber junction box

ONT = Optical Network Terminal (Huawei Echolife HG863 GPON)
This is where the fiber from the TP connects to. It has one fiber port and four Gb ports. No problem with it (so far)

RG = Residential Gateway (Huawei HG265s Wireless Router)
This is the part I am really stuggling with and is the source of all my efforts here. From the ONT Port 1 I have a CAT6 cable to the WAN port of this router. It also has four FE ports and two RJ-11 ports (I use RJ-11 port 1 for my phone). The problems I face with this unit are several: the firmware has been modified by my ISP so that the configuration is resticted. The port forwarding does not work. The DMZ does not work. The network ports are 100/10 (what is the use of having 1Gb?) The wireless range is really bad.

CMS is a CISCO SLM2008 8 port Gb managed switch

WR is a Cisco Linksys E4200 with DD-WRT

OK now, my ISP does not allow me to use any other router except the HG265. From what I have learned in local forums here is that it does this by using VLANs. As far as I have been able to tell there are at least three VLANs in use (there are actually more but I can't identify the use for the others), one for TR069 to manage the RG, one for my phone and one for internet.

I was able to log into the ONT by connecting to it directly. Although it uses a propietary OS and I am not familiar with the commands and/or configuration (and I also lack the skills to understand and use it safely) I managed to dump some (quite a bit actually, I didn't know what was important and what wasn't) information from it. It is included in attachment ONT.zip (only way I could make the filesize limit).

I got from another source that the VLANs are:
Internet VLAN ID:1071
Voice VLAN ID:1095
TR069 VLAN ID:1099

The RG is accessible by HTTP to the very resticted and almost useless settings. However I did manage to SSH to it. It has Busybox Linux and is also very limited (hardened?) so it lacks a lot of command and scripts.I managed to get some basic information from it:

What I want to do (or rather wish I could do) is to create the VLANs in the SLM2008 and have the RG only for the phone service and use another port (with the internet VLAN assigned to it) to connect my E4200 and use it as my router (with all the added benefits of DD-WRT.) Folks here in the Singapore forums have given up trying to achieve this (or they simply have lost interest, dunno.)

Thanks in advance!
