How to configure SBS 2008 network for new WAN connection?
We are switching from a standard fiber line to a dedicated line. In the past I’ve switched our IP address on our network without any issues. This time it didn’t work; we have no internet connection. I updated the interface in the SonicWALL 250M to the IP information supplied by the provider. I left the DNS addresses as they have always been set to my SBS 2008 box. Restarted the firewall and no internet connection. I checked for DNS settings in both the firewall and on the SBS 2008 box but I didn’t see where to make any other updates. I also don’t remember doing anything differently last time from what I did this time. We did verify there is internet connection to the new dedicated line so that isn’t the problem. We reset everything to how it was configured and we have access.
What am I missing?
Any guidance is greatly appreciated.

Can I run the wizard while we are online? I can't kill my users access during working hours.
From previous changes I have left the DNS setting as the IP of the small business server. If I remember correctly the SBS box wants to be the DNS server but where do I tell it what DNS settings to use, the Connect to the Internet wizard?

Thank you David for your reply.
I did have a consultant make some security changes to our firewall after the last time I rolled IP addresses/services. I was pretty sure this shouldn't effect the LAN side and I didn't remember ever having to use the Connect to the Internet wizard other than when we initially set up the server.
I will post what my findings are on any rules blocking us from getting to the WAN.

Agree on running the wizard. It will make all appropriate changes to the SBS config based on what it finds. you could also take a laptop, configure it with the static IP and connect directly to the internet connection bypassing the Sonicwall to verify internet. Assign Google DNS server addresses for DNS settings on the laptop Nic. If that's ok, then next config the laptop to connect through the Sonicwall. If that's ok reconnect the SBS and run the wizard

We have finally resolved the problem. It was twofold. We needed to update the firmware of the SonicWALL. That corrected the problem with the half vs. full-duplex setting. The other problem was working with Frontier to get them to actually get our settings right and verify the light was at the appropriate levels. Apparently we had dirty fiber as well as bad settings on their end.
We are now running at full-duplex and at the proper speeds, whether connected directly to the fiber circuit or running through our SonicWALL.
Just a side note; I never had to run the wizard.

cap all fiber endpoints as quick as possible. Just stopping for lunch is enough time for the fiber to get contaminated if left unplugged or uncapped. The end of the fiber is extremely small and dust or other contaminates are extremely large in comparison to coper. With copper the signal travels on the outside of the wire. We use a hand microscope to examine the fiber ends.

Thank you David. The "dirty" fiber was on Frontier's end not on our end. It took them a bit of time to trace it down. I agree on always capping the ends if left unplugged. Perhaps someone needed to tell that to the provider. Apparently there were also system settings on their end that was causing problems. My SonicWALL was only a small part of the problem.
Thanks again!
Thanks again!
