I have a question(s) that I'm sure are answered somewhere out there, but I am obviously using the wrong search terms.
We have 4 offices (each on their own IP range) that just had Charter fiber installed (ethernet handoff). Site A and Site B both have internet and WAN while Site C and Site D are smaller offices and are both only using WAN and will be using the other 2 sites for internet traffic as well. I have never used fiber before and I'm a little confused on how to set it up. We have SonicWalls throughout our organization and will be upgrading other offices to fiber as time goes on. Site A and B both have NSA 2400 and the remote offices have TZ200. We were given IP/subnet/gateway for the internet side but only told the port for the WAN side. Having only used VPNs and point to point T1s, this seems odd to me. My assumption is that I route the traffic for each office's range to one of the available ports on the SonicWall (let's say X2) but then how does it know where to go from there? It seems to me that there needs to be a routing table on the Charter side (Cisco used for the hand off possibly?). If this is so, shouldn't they give me that info or tell me that I'd need to call to have it done? Or am I completely off on how it all works? Please point me in the right direction.
Summary...
All sites need to be able to talk to each other.
Site C will be using Site A's internet connection and Site D will be using Site B's internet connection (due to proximity but maybe that doesn't matter with fiber?).
Site A is the site that matters most to the other offices as all of the billing software is hosted through this office.
Thanks!
