It was an issue of needing to reboot the modem, but also that the RB-750 was getting a different IP address via DHCP from the modem than the RB-750G was getting from the modem. I guess the IP address that's handed out is based on the MAC address of the client. What threw me off was each time I'd switch back to the original RB-750 it would get the same public IP address it's been getting for more than a year for it's Ether1-Gateway port. That made me think it was the only IP address the modem was giving out via DHCP so I was expecting the RB-750G to have the same address. But the RB-750G was getting random IPs each time I would have it put online. Once I figured that out everything worked out.
Thanks for the comments.
