New comcast gateway wired connection not working

[walterbyrd]

Comcast "upgraded" me to new XB10 gateway. Wireless works just fine. Wired connections not so much.
I can ping internet IP addresses. But I cannot go to a named website, like "google.com"
Comcast will not support FreeBSD.
I cannot login to the gateway. I have to do everything with their xfinity app.
I tried setting my name servers to 1.1.1.1 and 8.8.8.8 in rc.conf, but I got the message that those servers could not be found. I think the nameservers are set in the gateway, and I am not sure if I can change them.
I have my freebsd configured as a webserver, I can reach my local website.
I cannot bring up websites that are not local. For example, I can ping 96.47.72.84 but if I enter that address in my browser, the connection times out.
I have my freebsd configured to use static IP address: 10.0.0.9.
My local Jellyfin server also works.

Are you sure you can't access an administration page? Iirc Xfinity stuff had something odd like 10.10.10.1

I don't think it'd fix connectivity (missed where wifi works; looks like just FreeBSD-side conf needed), but putting it in bridge mode and having another device handle router stuff might be an option too (if a FreeBSD PC's the only device hard-wired to the modem, I'd have FreeBSD DHCP IPv4 + IPv6 SLAAC, bridge the modem, then try accessing the modem admin page and/or seeing if WAN works); this post says XB10 can do bridge mode

When I try to go to 10.0.0.1 I just get a message that my network are to managed with xfinity app. I they give me a link to xfinity.com.

I edited my original post to include this:

Irrelevant, it's TCP/IP.

I tried setting my name servers to 1.1.1.1 and 8.8.8.8 in rc.conf

Wrong place. Nameservers go in /etc/resolv.conf.

I think the nameservers are set in the gateway

You typically get an IP address, subnet mask, default gateway and one or more DNS servers with DHCP.

I have my freebsd configured to use static IP address: 10.0.0.9.

It's probably not the correct subnet. Just set the host to DHCP and let it automatically figure it out.
