If you are looking to install your QuickBooks on a cloud server the host of the cloud server might ask what ports LMN QB Sync needs access to, along with what the application requirements are.
The ports we use to access data out of the LMN Database before it goes to QB are the following:
- Standard HTTP and HTTPS ports should be open (80 and 443).
The application requirements are:
- QB SDK
- Just make sure that the firewall isn't blocking the LMN software
