I have a static IP and I wanted to set up another one. After calling up my ISP and getting another static address, I tried to plug a second router into my NetVanta 838T modem, but could not connect to the internet. I tried the new router in the first plug and it worked, so I think the settings are correct.
I called up my ISP and they told me it was not possible to do this with the hardware I have. Is this true, and if so, what is the purpose of having 4 ethernet ports on that modem?
