I think I've got a pretty good handle on my situation. So this may be a quest for verification rather than a question looking for an answer.
As the title states, I have 2 ISPs and each has multiple static IPs available to me.
Both ISPs and all computers are on the same subnet on the LAN side. (small office)
I'm using 4 pretty basic consumer routers to build my network. (d-link dgl-4100).
To "split" out one of the WANs to 3 of my routers, each using a separate Static IP. I've got the WAN plugged into a 5 port Gigabit switch. Then from there it feeds my 3 Routers, which then maps my ports as needed.
I know this setup is safe. Everything is behind routers and firewalls.
But is my 5 Port Gigabit switch unnecessary? Should I just be attaching the WANs to my Gigabit Switch along with all my computers? Or is that asking for trouble?
It seems that it would simplify my setup a bit and actually give me a bit of flexibility in terms of offsite trouble shooting (when I'm on vacation) if I could move someone that is having trouble to one of the Unused Static IPs (by telling them the manual config). That way there is no firewall or router blocking anything. Then switch back when I'm finished.
Again, I ask if I'm just setting myself up for trouble.
Thanks in advance.
