Hello, I was able to configure Eth1 and get the DHCP addresses now. It took a bit of practice as it's so different from consumer class type of routers but with your help, I have figured it out.
I have added 3 extra different DHCP pools to 3 other ports within the router for testing. They all appear to be working fine and I could hit the internet without issues.
Thanks again for all your help. This is why you're a "SuperUser".
