massively confused - Fibre broadband

[mudcow007]

So just had a fibre leased line from VM installed in work.

So basically VM have given us a Cisco 2921 router, which is fed from a Alcatel switch with a gbic (which the fibre goes into)

VM have given us 2 IPs

62.253.180.110
62.253.180.111

Also to add to the confusion, i have just bought a Sonicwall TZ400

I cant figure how to connect it all into our Lan - which is on 192.168.10.0

the IP's VM have given us our public, but they didnt provide us with Lan details of the Alcatel switch or Cisco router

Am I being stupid here???

do i need another router that will use the Cisco as its gateway that will have the sonicwall in between them all??

I'd expect that you would connect the Cisco router to your firewall's wan interface and setup all of your access rules in there (with your lan being connected to the firewall's lan interface) .


Both the Cisco and alcatel will be managed by vm and you won't have any access to them.

Indeed.

That router will want your ext fw interface on their configured port.

You then configure your fw ext address to match that provided by vm and internal addresses on another interface.

That alcatel is likely there to convert fibre to ethernet however that router should have spf capability which is odd... why use the alcatel. oh well!

To be honest the Cisco router is a monster (3U!!)......i'm use to using Draytek's an compared to one of them its a beast

it definitely has fibre channels but are unused!?

[P.addy]

Ah well. If they provide and set up the ntu just use that. No real issue.

am i being a dick here??!

so just had a replacement sonicwall fw as the first one was DOA

just trying to configure WAN settings

VM have given us the IP of the router which is 63.253.180.241

they also said we have the ip address 63.253.180.240 to use

on the Sonicwall wan config, i have set the router as 63.253.180.241 an where it says network i have used 63.253.180.240

the lan is still using the default of 192.168.168.0

i cant ping google from the sonicwall!?

am i being stupid?!??

[mudcow007]

yep i was being a dick

problem was 63.253.180.240

set it to 63.253.180.242 an everything is right in the world
