Turning off DHCP on ATT BGW210-700 Modem/Router
I just switched from another ISP with a separate modem and router to ATT Fiber to the combined modem/router unit. I have an Amahi Linux server that worked fine under the previous configuration, which entailed switching off DHCP on my previous router (which I still have) and letting the server manage the DNS. The new ATT setup seemed to be working fine with all my devices connected via wireless, except for the server which was directly connected to the modem/router. However, the server didn't show as a connected device on the modem/router and was unreachable by ping. I switched off DHCP on the modem router via the web app hoping that this would restore access to the HDA server, and promptly lost all internet access. With some fiddling I was able to switch DHCP back on and restore internet access, but I still have this problem of having a nonfunctional Linux server. Can anyone help me? I'm clearly out of my league here.
