best way to set up an office network

[ng12345]

I have a small business and I was hoping to get some advice regarding my network configuration.

I have 2 sites that communicate via openVPN that is running on a router at each site.

My main site has a server with 4 ports and 10 clients all connected to a 24 port gbe switch

My current set up at the main site is:
cable modem -> router -> 24 port switch

the router has a static ip on the cable modem network
the router provides ips for all the computers connected to the switch
the router runs an instance of openvpn to connect with the other site

Is this an ideal/suitable network setup (everything works fine currently)?
Currently there is the ISP IP -> cable modem LAN -> router LAN; should I eliminate one of these from providing IP addresses?
Instead of the server ports all connecting to the switch, is there any benefit to connecting one of the ports to the router directly or to the cable modem directly in making it more available to the other site? (the ports are all teamed together on the server side)

I don't see any problems with your current setup. Are you experiemcing latency on the remote site connecting to server? If not leave the network alone

Do you mean that the cable modem is performing NAT? I hate the idea of modems taking on routing roles because they are usually insufficient for performance and manageability so I always set them to transparent bridging for DSL but I believe cable providers dictate which mode their modems run in.

Looks good to me, but PliotronX makes a good point. What is the make and model of the cable modem? Lot's of them, especially business class from the ISP are modem only, but some are gateways themselves, and can give a sub-optimal situation. However, if everything is working without issue, there probably isn't any concern.
