I have a lot of IT experience/consulting, but want to test what I have done against some of the real experts hre in the networking field so I can keep learning and do what's best.
I have ISPs with 5 usable static IPs assigned. To split them so I can use separate IPs for particular usage scenarios, I have simply plugged in a small Netgear managed switch from the ISP modem, made sure the ports are running duplex and as high as they can go, and then from the Netgear plugged in and configured my main SonicWall with one IP, another two routers for some other work, etc.
Is this the proper/best performance way of splitting up the IPs? I ask because this method appears to work OK, but for a Gateway to Gateway VPN I have setup (one office has 100Mbs fiber up/down, and the other side is 50MBs up/down), I have found the performance a little underwhelming even for simple file copies between sites (can get no more then 10MBs, and then it seems to saturate the bandwidth, or CPU power of the router, dunno...). I am worried there is something asymmetrical in this approach. The routers for the VPN are Cisco RV042G and Cisco RV320, which frankly, am not sure are great routers to start with. I've assured by both ISPs there are is no throttling going on.
Hopefully this makes sense. Any constructive thoughts would be appreciated. many thanks
