Ugh, ok. I’ve been roped into an IT issue.
Small Business network. Connected to a home/business cellular modem.
5PCs and various devices on one Netgear router, with a wireless hub on one port. This connects to a wireless booster that connects to the house modem, which has various devices connected to it.
They’ve had some issues getting devices to talk to each other off and on. They’ve tried this and that to fix the issues, but it’s mostly resolved over time.
This particular time the POS PC has stopped talking to the Quickbooks server. I poked around some, played with making static IPs for the server and the workstation. (Server as in the Quickbooks definition, not a real server) I can sometimes see the server machine, but can’t always see the files on it. And can never keep the connection long enough to get quickbooks to link.
After poking around I find that they have a double NAT. The router in the office and the modem in the house are both providing that service.
I’ve been too out of this game. I’m really concerned if I turn the NAT off on the office router that everything will go boom. It should ideally be set up as a simple access point, leaving the modem to assign everything. But I don’t know exactly what happens if I change that and it dies.
All this from an office where three computers can see five machines and one can see two and the fifth can only see three.
4 windows ten machines and 1 windows 7.
Thoughts appreciated for going forward.
