TalkTalk IP's and gateway

[link to this post]
So, I recently renewed my TalkTalk Business account and requested more than 1 static IP address, so they are now charging me for 4.
First conversation with them afterwards was how to configure the supplied router with more than 1 IP address. It would seem this cannot be done (surprise!). So with a collection of Cisco equipment and a BT VDSL modem at hand, I went to configure as replacement config. Then I checked and found while I had details of four IP addresses there were no details on the gateway address required.
Second, third and fourth calls/online chats resulted in the following:-
You have reached TalkTalk Business support, how may I help you?
Me (16/05/2019, 12:12:40): Updating the firewall and need the default gateway address, it isn't shown on the supplied SuperRouter and this is being replaced
TalkTalk Business Live Agent (16/05/2019, 12:15:34): Default gateway is
Me (16/05/2019, 12:16:00): I doubt it, that's a private IP address
TalkTalk Business Live Agent (16/05/2019, 12:17:04): That's the gateway.
Me (16/05/2019, 12:18:42): really. So if I have an external P address of the gateway address is Can I talk to someone who understands IP addressing and routing, please
TalkTalk Business Live Agent (16/05/2019, 12:19:23): The address you may be referring to is not one we can access, we can only suggest you set the router to auto or dynamic and it will get the address.
TalkTalk Business Live Agent (16/05/2019, 12:20:06): You could try calling 08000833003 if you wish, or chat again and you may get someone else.

Second person:-

Me (16/05/2019, 12:48:20): the last guy suggested an external gateway address of ! this is getting silly for a business account
TalkTalk Business Live Agent (16/05/2019, 12:48:49): That is to direct you to the login page for a TalkTalk Business router.
TalkTalk Business Live Agent (16/05/2019, 12:49:13): Which would not apply in your case as you are switching to a BT VDSL modem.
TalkTalk Business Live Agent (16/05/2019, 12:49:58): Our 2nd Technical Support Team are not customer facing.
Me (16/05/2019, 12:49:59): Yes, I know and the TalkTalk routers don't allow you to access additional fixed IP addresses, only a single one.
TalkTalk Business Live Agent (16/05/2019, 12:51:07): I am sorry the information I have provided is not sufficient enough however this is the information I have found when looking in to your query.
Me (16/05/2019, 12:52:12): OK, so basically I'm being charged for something I can not ever use ! i.e. more than one fixed IP address
TalkTalk Business Live Agent (16/05/2019, 12:54:07): If the router is third party, we can only offer limited assistance as we do not support them.
Me (16/05/2019, 12:55:04): So, as I said, the supplied router/modem won't support it, and you will not supply even the basic network info to use a 3rd party one.
TalkTalk Business Live Agent (16/05/2019, 12:56:18): As your network provider, we are responsible for providing you broadband connection to the premises. The configuration of your router, if 3rd party, is not something we have information on. As I have said, The details you require should automatically configure themselves so long as the broadband credentials are correct.
Me (16/05/2019, 12:57:07): but without a gateway address the router can not send the credentials anywhere
TalkTalk Business Live Agent (16/05/2019, 12:59:01): We do not have this information. I am sorry about that.

Now two things here, they happily sell you 4 IP addresses (only 2 of which you can use), but more to the point the basic concept of
static IP address -> gateway address -> rest of the world
seems beyond their support!

I am having the same problem with talktalk.
They offer advanced business broadband services but then are completely unable to offer any support.

I have asked continually for the correct DNS, SUBNET, & Default Gateway information. None of which they say they are able to supply and keep telling me to seek specialist IT support. Not at all helpful.

I did manage to pull some of the info from my routers internet connection page, but this still did not tell me the default gateway address. When I asked talktalk for it they said that it is not information they give out to customers and that i can configure my equipment without it! Like how would this work?

If there is no default gateway specified the servers do not know where to send information or requests. DOH!

I'm now wondering if I can get out of my contract with talktalk as they either cannot or will not offer the support required for the service they supply.?

I presuming they have supplied a /30 subnet. It will most likely be the next IP address after the network address.
Eg network address:, Gateway , Useable You only have 2 options here so try it out and see which one works.

You could brute force reverse engineer it smile

For example connect a Linux machine up directly to the VDSL modem, get it working as though it had a single IP and then script it up to change the netmask/gateway and ping a known pingable external IP address. Exit when you get a response.

If they have given you a block of IP address then it should be relatively easy to work out a starting point.

That said they could be using something like RIP to distribute the routes.

Evening all.

Has anyone had any luck with this? We have exactly the same. We have been given 4 IP address's yet not subnet or gateway. Their tech support dont even know what is an internal ip address. We are also being told they dont have that information and that it shoud just work. I cannot beleive how little knowledge they have on this matter.

Ultimately we have been given 4 ip address's we cant use and cannot put another device on with a static address. Shocking!

Any feedback welcomed!

The post by Sammm_ above covers what needs to be done.

The subnet is determined by the block size and the LAN side gateway is from your own block depending what you set this to on your router. (The WAN side subnet and gateway are not required/set manually)

I suspect their stance on this is that the customer would/must have knowledge to configure this at their end and they simply provide the ability to do that with the block assigned.

Thanks. The above didnt work for us and talktalk were no use at all. We have it working now but had to reconfigure the vpn router to use the talktalk username/password and then run the original talktalk router through the vpn router.
