Looking for a different perspective from this amazing community. Variables:
Main Branch - Serving up business software SQL database driven. Does not take kindly to interruptions / dropped packets.
4 Branch Locations all within 70 miles (crow flies). Need constant reliable access to central db.
Current setup is VPN on single ISPs central location tunneled to branches. All ISP's are at least 30 down 5 up. No branch to branch access. Hardware is cisco rv320 smb router. Cisco unmanaged switches. Main is 10 pc's and 2 Servers (VM). 2-10 PCs per branch. Total of 40 at branches.
Main problem is branches losing connection to SQL database or extremely slow performance. Budget is less than 10k at the moment.
I have in mind a plan to remedy, but would like to see the community's take on stabilizing this. Any takers?
