Greetings,
My ISP was bought out and the new company is assigning us a new subnet to use. Currently they have set up our router to handle traffic from both networks until we can migrate DNS and domain registrations to the new network.
My goal is to have my NAT'd devices accessible from both external networks, so that there is no downtime.
Give then eth0 is my LAN and eth1 is my existing WAN connection, what's the correct process to accomplish this?
My first attempt was to create eth2 for my new WAN connection then replicate all my secondary addresses on this interface, plus adding new NAT and packet filter rules. Unfortunately when I try to connect to any of the devices on the new network the connections just time out (browser reports that the server is taking too long to respond).
I feel like I'm overlooking something very basic. Please advise on where to begin. Thanks!
