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.
