I'm trying to set up a Debian box as a router for an office. I need to have 3 subnets in the LAN and 2 WAN connections, and I want one of the subnets to ALWAYS use WAN 1 and the other subnet to ALWAYS use WAN 2 (no load balancing).
For exmaple, I want to have these three subnets: - 10.1.1.0/24 - 10.1.2.0/24 - 10.1.3.0/24
I want 10.1.1.0/24 to go out to the Internet using ISP #1 and 10.1.2.0/24 and 10.1.3.0/24 to use ISP #2.
And one second level of complication: ISP #2 is a DSL connection with a dynamic IP address.
I think this should be easy to implement, but I've never done it before and I haven't been able to find an example online. I've been reading lartc but I couldn't adapt the examples they provide to what I want to do.
I'll appreciate any lead!
