Having issues with IPv4 routing when using the goCoax MA2500D with my cable provider XB7.
The XB7 is the gateway at 10.0.0.1 and router with DCHP in range of 10.0.0.2-253.
When I connect my laptop to the goCoax I get a 192.168.0.x address and cannot route to 10.0.0.1, thus all IPv4 sites fail to be accessed. IPv6 works, ie Google, Amazon, ... works great! So the MoCA connection is working, it is a routing issue.
How can I fix this routing issue? Easy way I suspect is to buy 2 goCoax adapters, yet would prefer to understand why the XB7 and goCoax form a different network (192.168.0.x) vs the XB7 using 10.0.0.x for everything else.
Figured it out!
Solution: Add a MoCA filter to the input of my set top box (STB) to remove it from the MoCA network.
Reason: My (STB) is also a router: Gateway 192.168.0.1 and DHCP 192.168.0.2-xxx. This was causing some devices to receive 192.168.0.X IPs while others would receive 10.0.0.X IPs from the modem/route.
My MoCA home network includes:
- XB7 modem/router/wifi: Gateway 10.0.0.1, DHCP 10.0.0.2-250
- GoCoax MA2500D: Static IP 10.0.0.253
- Arris XG1-A set top box (STB): Gateway 192.168.0.1, DHCP 192.168.0.2-xxx
Could not find a setting to disable the router/DHCP in the Arris XG1-A STB so added a physical MoCA filter right at the coax connection on the STB.
