I have the following equipment, which I want to connect as described to two ISPs.
1 internet server - ubuntu 16.04 - to ISP 1
2 content creator - win7 - to ISP 1
3 HTPC - ubuntu 16.04 - to ISP 2
4 Sony BluRay player - to ISP 2
5 admin - ubuntu 16.04 - to ISP 1 -- needs to mount drives from computers 1, 2, and 3, admin both routers, and be a file server to HTPC.
I think what I may need is to connect it all to a switch, but I don't have one to test. Another possibility might be extra lan cards, or wireless cards.
What would be best, and are there any pitfalls I need to avoid in the topology?
If I need to supply any more info I'll be happy to do so.
Speaking of which, as a pre-edit if you will, everything is in one 16x16 room, mostly on one wall.
ISP 1 is suitable for the server, whereas ISP 2 will not provide a properly formatted reverse DNS. AOL and Comcast mail servers insist on that.
ISP 2 gives me more bandwidth, so that Netflix etc. don't detract from our customers' experience.
Both routers are set to 192.168.0.1, but that can change, of course.
