Business SuperHub Question
 

Hi,

Does anyone know if the Business Superhub's support a "Multi-NAT" function?

if not would the business team be able to supply a device that has the "Multi-NAT" feature?

This is for the 50MB Business Service that is due to be re released arround October Time

Regards

I cant say for defo because I honestly dont know but I would bet good money the answers are no and no.

Re: Business SuperHub Question
 

In essence on its own no it can't if you mean you want multiple public IP addresses mapped to it in NAT mode then no.

In multiple IP mode the Superhub performs no NAT at all. It just routes all of the IP addresses you have through to the LAN side.

However if you have a router behind the Superhub then you can achieve this.

I do it now with a Cisco 892W behind a business superhub in NO NAT mode as I have a routed subnet from VMB.

Re: Business SuperHub Question
 

I was going to say, Cisco routers can do it without breaking a sweat but there is a big difference (in fact i think you cant even begin to compare them) between the shub and Cisco routers.

It is one thing trying to fob residential customers off with a basic router but how they got away with it for businesses is beyond me.

Well in no NAT mode while it is still routing it does a lot less so seems to cope :-)

Oh right that's interesting I was told in order to use my draytek router I would need a superhub that has "Multi-NAT"

Draytek email support said I wouldn't be able to do the following

1. Assign a public ip address to the super hub
2. Assign a public ip address to the draytek router
3. Assign public ip addresses to LAN clients connected to my draytek router

I'm planning on having a simerler setup to yours except my router is a draytek not a Cisco router

If I take the 5 ip option would I still be able to do what I said wasn't possible ( see my post above) ?

So does the superhub not perform NAT when multiple public ip addresses are used ?

Re: Business SuperHub Question
 

You will certainly be able to do number 1 & 2 if you take the 5 (or more) fixed IP address option yes.

Option 3 depends how you plan to subnet it down.

Re: Business SuperHub Question
 

1-3 are all possible. Draytek are talking bollocks. And not the first time either

Re: Business SuperHub Question
 

Well I cant get a public IP on the WAN side of the superhub, so if you would care to shed some light....

Re: Business SuperHub Question
 

Ahh right wouldn't the LAN clients (that I want to assign a public ip address) use the same subnet as the public ip address ?

How would I go about setting up the routed ip setup on the draytek router (any ideas) I would just put the super hub's public ip address in wouldn't I ? And put the public ip subnet in

And on the LAN client I would put the superhub's public ip address as the default gateway

Am I right ?

How would I setup a public ip for the draytek router as in the quick setup it asks me to specify an static ip address and I was told to put in the internal class C address would I put the public ip address (of the superhub) instead of a private address

Re: Business SuperHub Question
 

If you use the Business Superhub in NO nat - ie routed subnet mode it will not run a DHCP server, so you need to statically assign your addresses. The first int he block will be assigned to the superhub itself. Yo ucan then assign another statically on the draytek

Re: Business SuperHub Question
 

I dont know about draytek routers but if you got yourself a Cisco router you can save yourself a whole lot of trouble. If you have got more devices than you have ip addresses (e.g if you have got 4 public addresses) you can create a dhcp pool for your lan and tell the router to nat the private addresses to the specificied 4 routable public addresses. It is very good.

Re: Business SuperHub Question
 

Oh right thanks for the advice everyone

I will have to give it a go when the service comes out

I will email draytek and tell them that the super hub does not operate in NAT mode when you have routable ip addresses


Thanks

Re: Business SuperHub Question
 

I've just got a reply from draytek and this is what they said

Im guessing public ip addresses can be passed through the super hub am I correct ?

Yes.

The Superhub can't *not* pass them through when you have multiple IPs.
