Re: Switching IP address ranges

Another possibility is simply to place the Sonicwall in between
the Internet and the SBS's WAN card rather than disrupt the entire network.
I have changed LAN IP subnets more than once on some relatively small SBS
networks and it is tedious work with LOTS of potential for error. If you do
this, be sure to shut off your cellular phone and expect an evening of total
down time, even if you can use the SBS 2003 Change LAN IP wizard, which I
imagine does a decent job of fixing the SBS but may not cover the rest of
the LAN well,depending upon what's there. You'll have to take an inventory
of every IP device on the network. Even at that, chances are some detail
will be overlooked. I would not do this without a very good reason. (My
reason was inter-client VPN capability; I just have to be able to VPN from
any of my clients to any other client, and that requires that they all have
unique LAN subnets.)

And yes-- if the Sonicwall can't be reconfigured for 192.168.16.x,
then it's almost worthless. Even a $50 router has the capability of picking
a new LAN IP subnet. I'd change the Sonicwall before changing anything else.

Hi there,

I am having a security device added to one of my small business networks
which requires me to change the I.P. address range on my SBS network from
192.168.16.x to 192.168.Something else.x - sorry for the terible notation
and spelling ;)

I am using SBS Premium which currently uses ISA but ISA will be replaced
with the sonicwall and my SBS will be in Single NIC mode.

Anyone got ny hints on the best way for a smooth transition?
