Assigning two seperate IP ranges
Posted on 2009-07-13
We have hit a potential issue - we're running out of IP Addresses in the externally assigned range. We've spoken to Time Warner Cable who provide us with our ethernet connection and they've said they can assign us an additional range, but it will not be sequential from the current range.
All fine with that, we don't really care - we just need more IP's.
Problem being, the Time Warner ethernet connection plugs directly into one of the ethernet ports on our Sonicwall (Sonicwall 3060 - assume latest firmware, if it's not we can update it without issue). From what I can see, there is no way of assigning two external IP ranges to the same port on SonicOS.
My question would be, what would we need to purchase / do to allow the Sonicwall to use the two seperate ranges, even though they're being delivered on the same media - note, that if this involves buying a router or such to sit between the Sonicwall and the provider, then that's fine.
A thought that's just come to me, would it be as simple as hooking the delivered ethernet connection into a hub (taking layer 3 out of the equation) and then two ports from the hub into two interfaces on the Sonicwall and assigning their seperate address ranges?
