Mitel MBG and Draytek 2925

[jclem]

Hello all,

Apologies as this is a cross post from another forum.  The company who installed our Mitel won't touch our Draytek router (as it is not Cisco) so need some advise. To add some more complications the MBG is a virtual server within VMWare.

So as I understand it the MBG needs one internal IP and one external IP. Within VMWare I have given the VM two NIC's, one connected to the normal network and one that connects to port 5 on the Draytek. Our standard subnet is 192.168.6.x and so I have given it a local IP address. I have a spare external WAN IP Alias which I can use but have no idea how to set it up on the Draytek so it will at least pass the MBG connection test. Many have suggested DMZ but I've just been told to investigate one to one NAT with a dedicated external IP?!

Many thanks,

James

I have used drayteks a few times.
Not on this exact model.

If you look a the pic attached you can see the "2nd lan" is programmed. (mine is disabled at the mow but you should enable yours)

Put your public ip's and subnet in here

The ip will normally be the routers public static address that you already use.

When this is programmed you can then set a public ip directly on the Wan side of the MBG and connect it to any port on the draytek (no vlans)
Set the subnet the same and the gateway is the public ip of the draytek

If any of this not clear i can go into more detail

Hope this helps

Hi,

Thanks for the reply but I have a few questions. On your picture are you referring to the "For IP Routing Usage" box? And the information I put in there is the WAN IP alias that I have decided to use and the subnet from the WAN settings page? And then its that simple?!

James

For ip routing. Correct
The ip is that of the router not the Mbg

I presume the dray trek has a public static address already. Put this one in 2nd routing.

If you have the public IP address that you want to assign to the Mbg in the alias list, take it out.
Yes it's that simple

No firewall rules needed or open ports. Under normal conditions.

I have 8 WAN Ip alias' which range from X.X.X.129 - X.X.X.137. I was going to use X.X.X.134 for the MBG. So stick that in the IP box and then the WAN subnet in the box below. Then set that IP as the public one when you configure the MBG server. If any of that is wrong then please correct me, if not then thank you very much, your help has been much appreciated.

No
The only place the Mbg public ip goes is on the Mbg prigramming

What is the public IP address of the router? 129?
If so put that in the draytek 2nd LAN

Good luck

I think I'm in above my head a little. Made the changes on the Draytek, on the new 2925 that option has moved slightly but I'm fairly sure it is set right.

Now when I configure the MBG I set its internal IP and then external IP (X.X.X.135) the subnet (255.255.255.248) and the gateway IP address (X.X.X.130). It still fails the connection test?

Subnet mask 24? Typo?  If u have 8 public address it won't be 24. Use "online subnet calculator.

Putty to Mbg Login as root. Same password as admin
Can u ping the Mbg public address. Can u ping the draytek public address?

If u never used putty goto

Just to clarify slightly, the WAN connections gateway IP is X.X.X.129 and the WAN IP is X.X.X.130 with aliases from 130 to 137

In the IP Routing section I have used X.X.X.130

On the MBG setup I have tried both X.X.X.130 and X.X.X.129 but neither work.

I've just realised what you meant about the subnet. We recently increased from 4 public IP's to 8. I'll get that changed. And then i'll try putty. Thanks for all the help

[pmhaynes]

Mbg can't be 130 or 129. Try the next spare 131?
If route is 130 then in the Mbg set gateway as 130

Must have subnet correct
Something like 255.255.255.248

Because I have 8 WAN aliases then I think the subnet needs to be 255.255.255.240. I've changed it to that on the router and its still working.

[pmhaynes]

Cool. Same subnet on Mbg. Can u ping router?  If so ping something like 8.8.8.8. Then chk DNS by ping a name

Where do I ping from? I can't putty onto the MBG - it keeps saying connection refused?
