FTTC modem IP address


[link to this post]
 
Well, our PCP went AO on 1st Jan, so I've ordered FTTC (Plusnet unlimited), although I'm sure that no power has been provided, (can see it from my bedroom & no activity at it since install & duct to existing PCP footway box in March 2012).

The FTTC cab appears to be an ECI unit, so I expect I'll be given an ECI modem.

I'm sure that it's been mentioned here a while ago, that the modem IP address is 192.168.1.1

Sorry. Trying to type & watch the TV. Looks like I can't multi-task frown

I should have asked if that IP address for the modem is correct ??

I reckon so. The Huawei is that, so for interchangeability it would be the only safe setup. Bear in mind the biggest customer is some firm that sends out Home Hubs for managed install, and those are 192.168.1.254.

I've not heard any mention of the ECI being elsewhere in that subnet.

I've always used 192.168.1.254 as the router address, mainly due to using the BT laptop, which used fixed IP & that router address.

My whole network uses fixed IP & my server is on 192.168.1.1 (hence my interest in that address).

For the first 10 days, I'll use the Openreach modem & Plusnet router, so as not to upset the DLM, etc. Beyond that time, it's back to the Draytek Vigor 2850Vn.

Openreach DLM doesn't have a 10-day period. In particular, MSR and FTR which the BTW one sets at the end of 10 days on ADSLx don't feature on GEA. That being the only relevance of the 10 days.

What you could do is get another OR modem now and unlock it. Huawei is easy, ECI a bit messier but I wouldn't be surprised if you could handle it easily.

You could change the IP address of that, and substitute it right at the start - or at least as soon as the engineer walks out of the door if that's simpler.

Unlocking the Huawei takes a few careful minutes, that's all.

From my perspective, I'd rather have the modem unlocked on day 1. I'd specifically want to see the initial line statistics before DLM, and watch the resulting DLM intervention in the first few days.

I'd value knowing this information above any accidental triggering of DLM that I may inadvertently cause!

But I may not be normal wink

I'll have a look on Ebay. I know that the Huawei modem can be unlocked easily.
I also noticed a few weeks ago, that there's a hack for the ECI modem, but not a easy as for the Huawei.

I could always change the server address, but there's alway one config change that may get missed & then there's no mail, website, etc. frown

Once I sure (a week or so) that everything is working fine & is stable, then it back to the Draytek.

The modem won't be on your network so the won't be a conflict.

Frankly, that's what I've always thought.

I've never needed to run a network with a modem & a router, (it's always been a modem or router) plus running a server 24/7, I wasn't about to risk it not working.

Sorta true..

Doesn't the router in this case form a PPPOE tunnel to the modem? if that has the same IP as a machine on your LAN, how does the router know which interface to use? (IE. LAN or WAN ethernet interface)

Probably possible with a static route or depending on router options/abilities, so whilst your modem won't be on the internal network, the router will see both.

We do not do this in Enterprise, you should have them in a different subnet, even if just for neatness.

It is if you are connected to it through the second LAN port.

That is dealt with by allocating an appropriate IP address to the modem that is within the network range but outside the DHCP allocatable range. Takes a matter of seconds once the firmware is updated.

The router can't see the LAN side of the modem through the PPPoE connection.

No.
The pppoe connection sends ethernet packets between the router and the modem, but these are not IP packets and have no IP address. All the router need to know is which interface to use, not which IP address to connect to: e.g in my rouer I have "plugin pppoe eth1" in the ppp configuration, no need to mention an IP address as the interface name ("eth1") is the only information needed (this is for an ADSL router in bridge mode, but pppoe is the same for everybody!). The only IP address involved will be the one obtained while setting up the PPP session, and that has nothing to do with any IP address assigned to the modem itself - I suppose you could refer to it as a PPP tunnel to the ISP using PPPoE - all the modem is doing is encoding/decoding packets to/from the VDSL link, without even looking inside the packets (*).
Of course, if you mean that you need to access the modem for configuration/statistics, this will need a static route to the modem - otherwise the router will send IP packets which you mean for the modem itself over PPP to the ISP and that won't really work. What will happen in this case is that you bave both pppoe packets (headed in the direction of your ISP) and IP packets (headed to the modem) on the same interface. This will cause no confict.

(*) "without even looking inside the packets"... with the possible exception of a qos setting which will need to look inside the packets to decide how to deal with them, but that's irrelevant and I'm only mentioning it before some other pedant does.

I had a feeling that it would fail.

Plusnet emailed me yesterday, saying that Openreach had informed them, that the cab didn't have working fibre after all frown

So it's now showing as 31/3/13 & not AO.

Working Fibre - that could mean that fibre is installed and as you suggest, no power! Can you get more details ? There could be a lot of reasons - no sub-con available, local authority will not give approval to close road, it is a long run for the power ...

I presume by not having working fibre, they mean that it's not up & running.

FTTC cab was installed last March, & duct dug in, over a couple of days.
There was an Openreach gang installing sub duct / blowing fibre at about the same time, but atleast one other fibre cab is fed via the same E side duct route, so may / may not be for my cab. The other cab has been up & running for a few months now.

As I look a the cab each day from my bedroom (just down the road about 50 - 75 yards), I haven't seen any contractors doing the power feed, & the only new tarmac is to the Openreach footway box.

It may already have it's mains power cable connected up. They put the power in to cabs once the cab & ducting is installed, then backfill the holes in some areas, to save money most likely,
But may also depend on which company does the install, and if they have an engineer who's qualified to carry out the electrical connection
Sounds like it maybe in need of it's fibre spine, that was done last around here

Nope. The only new tarmac goes straight to the main PCP's footway box, about 2 metres away..

No other trench has been dug.

where from the FTTC cab? if so that will be the duct for the PCP links The ones they did in my area, mostly had 2 or 3 trenches, one to pcp, and another to the foot way box , and power,

Most around this area have 2. One to footway box & the other for power.

Don't need for one to PCP, as link cable will go via footway box. That PCP has plenty of spare duct capacity to the footway box.
