BT2700HGV Router Details

cliveh — Mon, 13 Feb 2012 16:55:26 GMT

Hi.

I have started to implement content screening, but it appears to be a blanket allow / block. However in the content screening menu I can see various devices attached under the computer heading.

I would like to add another device for a user who requires access to some of the sites I have blocked, but can see no way to add a device.

How does the router determine these devices, and is there a way to add a device?

A couple of the devices are PC's that are attached to our network.

The BT Router connects to our CISCO Firewall and so all network devices need to pass through this protection before going out through the BT Router.

Any clues please?

Thanks,

How many gateways do you have in your network? You can probably route a specific source IP to a gateway with no restrictions.

This means you need to assign static IPs on all PCs on your network.

The router detects new devices and adds them to the list and you can then allocate them to Group1 or Group2 for content screening.

You can select the last one on the list "New Computer" and give that strict screening so any new device user will need to ask you to free up access.

too many devices to go with static ip's. I'm afraid. Thanks for the help though.

how does the router detect new devices? i have a few of our networked pc's being detected but not all of them. I'm pretty sure that the detected devices have not been connected to the router at some stage. If I attach the laptop in questions then will that setup the account under the computer section?

Where are the devices getting their IP address from? They will normally need to access the router for that - inless your DHCP server is elsewhere.

Yes, attached a laptiop - you may need to do it twice withh wired and wirless and they will have different MAC addresses.

DHCP from Domain Controller.

OK will try and attach the laptop as its user specific and see if I can put that device on to group 2 which has no blocking control.

Thanks for your help. Will let you know how I get on.

Cheer.

ok added the device to the Router settings and have associated the device to a No Restrictions group, but the user is still not able to access the websites that I have blocked within group1.

I have a feeling that this is not going to work and I may need to look at a web proxy appliance rather than the BT Router.

Unless you know otherwise.

Cheers for all the help thus far.

Clive.

Have you used the SAVE button after each change?

On occasion I've found that if you're applying access control rules but they're not being adhered to, then best thing to do is clear the device list and re-set them up again. Not exactly a quick-fix but seems to be the most effective. Go to Settings> Diagnostics> Resets and clear the device list, once the devices are rediscovered add them to the appropriate group again. The other knock-on affect of this is any port rules currently in place will need to be re-added again.

don't know if this coincidental, but since activating the content screen service, the BT router has now started to reboot itself intermittently.

Anyone else had this issue.

Re: BT2700HGV Router Details

If it's rebooting intemittently, there must be an issue. Have you treried checking the error logs? Could be possible that it is running out on memory because of huge entries of input.

have found this is the error log, though doesn't seem to indicate memory.

Have rang support who are saying its an internal issue. I have been asked to take the cover off the ADSL v1.0 box which is where the main cable comes in and run the connection via the test socket. There is no test socket and the wires are bare and don't appear to be securely fastened to the socket, looks like the socket presses against the wires to make the connection, does this sound correct?

Re: BT2700HGV Router Details

MHC — Wed, 15 Feb 2012 23:42:34 GMT

Can you get a picture of the internal part of te socket ... you can post an image on here and then we can comment.

Also, on the 2700/2701 is a page with the training history - statuas when sync lost and regained ... home/xslt?PAGE=C_5_3 that can be useful in seeing what te line state was when sync was lost.

spoke with BT yesterday... they called me. woohey!

anyway the guy I spoke to Steve was very knowledgeable and said that it sounded like a power issue, so he is sending out a new router and power supply. The new router still does not have the ability to save the config, however he did also say that there was a brand new router that it is trial status at the moment that does have the ability (about time too).

Will need to configure the new router with the existing settings (manually), so have to make good screengrabs of the relevant pages, wish me luck. lol.

Thanks again for all your help.

The 2700/01 does have te ability to save te config - how else does it come back in the same state after a power cycle? It does not have the ability to take a copy of the config file and dloiad that elsewhere but that is not a major issue.

yes the config can be saved to running memory, but the ability to take a copy and then upload that copy to a new router if there is a problem would be helpful in my case as I have 8 static ip's that link to public facing services and setting these up each time can be resource consuming.

Have received and installed a replacement BT Router. All was ok for one day and then today we have had one outage, though whilst BT were doing their tests and checks the line was going up and down worse than anything.

Have arranged for a BT Broadband Boost Engineer (very grandiose) to visit next week.

Re: BT2700HGV Router Details

i have a suspicion that our issues lie with the implementation of content screening and the higher than average load that this places on the 2701 router.
