Using the Technicolor TG582n in Bridge Mode

[#1]

No, you can use any of the 4 ports.
I've not tried with the IPv6 firmware. You could install the 8.4.4.J firmware, it works with that.

Snap, I was about to query whether the telnet commands posted by solidsystems are firmware version sensitive too?

fwiw, I have put the same telnet commands onto my surplus fibre TG582N (flashed down to 8.4.4.J ADSL version) earlier this week, but not yet taken it around to another site to install on a BT ADSL2+ line.

[#3]

Flashed to 8.4.4.J and ran the commands still not working for me when I get on the router broadband connection is BrPPPoE_br connection info is bridge up for 12 mins with a green tick DSL connection also have a tick. Check connectivity only gives a tick to DSL. No light on internet which on the router itself which I think is correct. When I try logging in with dd wrt it just seems to try and connect and then goes back to saying disconnected
Any other suggestions, been there nights think it might be time I buy a modem

Just noticed service name is PPPoA on 0/38 (modified by user)
Should this not day PPPoE?

[#5]

Regarding the command line:
atm ifconfig intf=BrPPPoE_atm dest=BrPPPoE_ph encaps=vcmux ulp=mac

When I have used 2wire routers in bridge mode, 'Bridged LLC' setting was the recommended encapsulation for use with PPPoE.
MisterW quoted in an earlier post, http://www.mattturner.plus.com/bridge.tpl for TG585. This contains this line within the [atm.ini] section:
    ifconfig intf=atm_Internet ulp=mac encaps=llc
The above line is also found in Zen's template for using bridge mode on their TG582N.
MisterW went on to suggest that the encapsulation method perhaps did not need to be changed (to vcmux)
So would this be the correct telnet command line to use:
    atm ifconfig intf=BrPPPoE_atm dest=BrPPPoE_ph encaps=llc ulp=mac  
Unfortunately, I don't have ADSL here so can't test it.

Thank you soo much, three nights trying this the llc issue was the one! all working now. below are my settings in case anyone else is struggling. only line which is different is the encaps line!

ppp relay flush
ppp flush
eth flush
atm flush
atm phonebook flush
saveall
atm phonebook add name=BrPPPoE_ph addr=0.38
atm ifadd intf=BrPPPoE_atm
atm ifconfig intf=BrPPPoE_atm dest=BrPPPoE_ph  encaps=llc ulp=mac
atm ifattach intf=BrPPPoE_atm
eth bridge ifadd intf=BrPPPoE_br
eth bridge ifconfig intf=BrPPPoE_br dest=BrPPPoE_atm
eth bridge ifattach intf=BrPPPoE_br
service system modify name=DHCP-S state=disabled
wireless radio state=disabled
saveall

I can finally confirm too that my ex-Plusnet fibre TG582N downgraded to v8.4.4.J (ADSL version) is working fine in bridge mode too on a BT ADSL2+ connection at another location, using same telnet commands as trouty500.  It is connected to a cheap cable router running DD-WRT set up to use PPPoE with MTU=1492.  I couldn't use the TG582N as a 'router' because you cannot set up port forwarding to LAN devices which have a static IP defined on the actual LAN device.

Hi. I would like to make the same modification.
Question: do I need to downgrade to v8.4.4.J or can I also run it on 10.2.2.B? And if I need to downgrade, where can I find the firmware file to download?
Thanks! Great thread here, really helpful!

[#9]

Perhaps you can test the telnet commands on your TG582n and report the outcome?
Otherwise, all the Plusnet TG582n firmwares can be found here:

[#10]

This little tip perhaps deviates slightly from the subject title, but if you have a router running DD-WRT connected to your TG582n in bridge mode, I discovered it is possible to access the TG582n web interface or use telnet. eg. to check line stats etc.
Instructions can be found here to assign a local IP address to the WAN port of the DD-WRT router.
http://www.dd-wrt.com/wiki/index.php/Access_To_Modem_Configuration#Primary_Method

The Plusnet TG582n can be reached either via the default 192.168.1.254 address, or an alternative 10.0.0.138 address.
In summary:
If your DD-WRT router is configured by default to use IP address 192.168.1.1.
You can therefore use the following 'startup' and 'firewall startup' commands described in above link to access the TG582n at 10.0.0.138 by assigning 10.0.0.2 to the router's WAN port:
ifconfig `nvram get wan_ifname`:0 10.0.0.2 netmask 255.255.255.0
iptables -t nat -I POSTROUTING -o `nvram get wan_ifname` -j MASQUERADE
If your DD-WRT router is configured with an IP address on a different subnet such as 10.x.x.x or 192.168.2.x for example.
You can use these alternative 'startup' and 'firewall startup' commands to access TG582n at 192.168.1.254 by assigning 192.168.1.2 to the router's WAN port in this example.
ifconfig `nvram get wan_ifname`:0 192.168.1.2 netmask 255.255.255.0
iptables -t nat -I POSTROUTING -o `nvram get wan_ifname` -j MASQUERADE
I don't have an ADSL line here, but the above startup commands appear to work for my DD-WRT router connected to an 'off-line' PN TG582n (bridge mode).  I've tried it with the DD-WRT router configured to use IP addresses of 192.168.1.254, 10.0.0.1 or 192.168.2.254. 
I will test it with an ADSL line at a later date, but if anyone is able to confirm this indeed does work, please let us know.

I can confirm that the commands also work with the latest firmware, i.e. 10.2.2.B. It currently feels really slow, not sure if this has to do with using the router as a modem. Could be because I had to disconnect a couple of times.
I will be back here posting if the slow speed persists.

Hi folks, thanks to the OP and the subsequent additional info posted here.
I am also on 10.2.2.B, just received my router, at a new house. The process here http://community.plus.net/forum/index.php/topic,105753.msg1062794.html#msg1062794 is not working for me. I am on regular ADSL (not fibre).
Strange thing is I am getting a WAN IP address at the my Netgear router so I must be doing something right! But no internet connectivity from my laptop connected wired/wireless to my router.
Am I correct that it is ok for the Netgear router to be on 192.168.0.x when the TG582n is on 192.168.1.x range? I am not keen on changing the router to 192.168.1.x because of the setup I am bringing with me that sits behind the Netgear.
Anyway, I will try the 8.4.4.J firmware and report back.
cheers
Paul

@coople
The gateway address for the internet is 192.168.1.254 any devices on 192.168.0.x will not be able to access that gateway address because they are not on the same network address range.
You could look to change the TG582n to 192.168.0.254, but you need to check you do not create any duplicate IP addresses by doing this.
Dan.

[#14]

Thanks Dan. Although I was able to re-assign the plusnet box's IP range to 192.168.0.x to match my Netgear router, I was still not able to get the Netgear router fully working as a router. I since found that it was possible to assign specific static addresses to specific devices and this means that I do not need to get my Netgear router working. So I'm giving up on making the plusnet box work in bridge mode in my environment! Next step is to re-purpose my Netgear router to extend my wifi to the deeper recesses of the house...   Thanks again

coople, if you use the TG582n in bridge mode (or as a modem, to be technically correct), it will not get an IP address. You'll get the assigned public IP address on the WAN port of your router that you are using for the PPPoE connection. There you define the range of IP addresses that you use for DHCP in your own network.
I'm still experiencing rather low speeds at times with this configuration. It helps resetting the connection, which is cumbersome however. Does anybody have similar experiences?
