Hello all my friends
see picture to understand my problem
i want to know that how my company can connect multiple isp via switch and output from switch is directly connected to linux firewall.
Any help
Thanks
I would not connect the different ISP's into one switch. You don't want your ISP's routing between each other there before they even talk to your server, and putting three ISP's through one cable could bottleneck your speed. I'd add three network cards to the server instead, and plug your ISP's in individually.
How to route them to your users depends what you want to do. Who gets to use what ISP for what?
