6120 setup
I need to connect a comcast cbr-t router/modem to a tp-link er6120.
The comcast router has a static external ip address that I must be able to reach.
The comcast router is currently set up to hand out ips in 192.168.1.???.
I have 6 ports forwarded on this router and they are all accessible through the static external ip address.
Comcast has informed me that if I put the router in bridge mode I will lose my static ip and wifi.
I need the static ip. I can live without the wifi.
I wish to use the er6120 to act as a failover device for 2 different internet providers.
I don't need load balancing or vpn.
I would like to keep all workstations, printers and other devices on 192.168.1.???.
I was doing the failover manually with 2 router/modems set up identically and just unplugging one from the network and plugging the other one in.
It worked, it just wasn't automatic.
I set the er6120 lan to 192.168.2.1.
I set wan1 to static and entered my external static ip, gateway and dns numbers.
I don't get internet access.
It tried dynamic ip.
It picks up
192.168.1.77
255.255.255.0
default gateway 192.168.1.1
dns 75.75.75.75
dns 75.75.76.76
All of my workstations that were picking up an ip from 192.168.1.??? are now picking up 192.168.2.???.
I assume that the er6120 is handling all dhcp.
It gives me internet access on my workstations that pick up a dynamic ip in 192.168.2.???.
I get no internet on any of my statics in 192.168.1.???
What do I need to do to get internet on all workstations?
How can I keep all of my devices in 192.168.1.1?
I realize that I have a double nat going on.
I don't care about the port forwarding right now.
I just want to get wan1 working for all devices.
I will deal with double nat port forwarding and adding wan2 when I ge wan1 working.
