Hey,

Im on telecom adsl with the supplied modem/router thomson tg585v8. This router is absolute crap so I bought a new one before I realized telecom is on PPOA. Now I have a asus rt-n56u and am having trouble setting it up. I want to use the thomson as just a modem, absolute bare minimum usage while the asus handles everything else. I bought a new router because of the dualband 5ghz wireless n and the QoS for gaming and low prioritizing P2P.  

The only way I have got it to work currently is half-bridge by assigning a public ip to a device. This does double nat, one through DMZ, and to me it doesn't seem the best option. I then read about PPTP passthrough which is apparently better so I am trying to get that to work.

Heres some pics of what I have done for my setup.

Internet works now but is INCREDIBLY SLOW. I think i have done something wrong. I am back on half-bridge now but if anyone can help me get PPTP working so i can use my new router it would be much appreciated.

I don't have a Thomson around any more so can't give you any specific advice... but also heard another person who recently tried to use PPTP couldn't getting it working well either.

You could try contacting the guy that first posted the cmd's for PPTP on the Speedtouch NZ forum
http://www.speedtouch.net.nz/forum/topic.asp?TOPIC_ID=1239

Otherwise NAT with DMZ to the Asus is probably the best achieve can do with the Thomson.

Replacing the Thomson with a Draytek Vigor 120 that does full PPPoA to PPPoE bridging or with a TP Link TD-8840 (or Dynalink 1320E or Dynalink 1320 modded with cheap jaycar heatsink on the main chip) that does a half bridge that doesn't cause double NAT would be my advice.

Thanks for the reply. My family are getting quite sick of the internet downtimes when I am messing with PPTP so I think I might give up on that if others couldn't get it to work as well. I have set it back to half bridge and once again its working full speed. They draytek vigor looks really nice, I think I may end up buying it. I didn't want to buy a new modem because I am moving out soon and am unsure if ill be on cable or adsl so didn't want to waste any money. True PPOA to PPOE bridge is so nicee. Lol it's settled I am going to buy it and throw away this piece of crap thomson so no other unfortunate soul gets it.

I have a TG585 V8 acting as a modem on an ADSL2+ service and connected to a Linksys E4200 via Ethernet two host (255.255.255.252) network and it works super fine.

You'd be surprised how configurable the TG585 V8 is.

I thought the TG585 V8 was pretty fly as a 2.4Ghz 65Mbps modem/router.

FYI his first screenshot shows the commands he used via the CLI to enable PPTP.

Sorry, was on an olde worlde mobile and didn't look at the imges.

[Slinks off back into hole in the ground...]

I've only used double NAT with the TG585 thus far.

BUT I'll be going down the road less paved with VPNs into my NAS soon.

ISP -> TG585 ->Linksys E4200 -> NAS

Guess it'll be tears before bed time... I'll be back.

Bought Draytek vigor 120, set up PPOE passthrough and the Asus RT-N56U is working perfectly! Just had to log into the draytek modem and tick ppoe passthrough then log into my asus router and set to ppoe and enter my user/pass. So simple. Much faster wireless and my gaming latency is a bit more stable now.

I am unable to enter the draytek settings though when I am plugged into the asus router and it is set to PPOE. I was able to when the draytek was setup with my telecom user/pass and router set to automatic ip. Doesn't really bother me but is there a way I can still open up the drayteks settings when I am plugged into the router with ppoe-ppoa passthrough?

Yeah in PPPoE the Asus doesn't know it can get to the modem's lan ip address out it's wan interface, if the Asus has the option you should be able to add a static route in the admin ui somewhere.
