ISP router - aaa.bbb.188.161 (my routers static 0.0.0.0/0 route)
My Router - eth0 has 2 IPs
aaa.bbb.188.164
xxx.yyy.195.225
ISP is routing subnetX to my router IP aaa.bbb.188.164.
When I put a server on subnetX with a gateway of my router, xxx.yyy.195.225, I can ping my router subnetA but not the ISP router on subnetA. I can’t ping anything from subnetX other than other devices on subnetX and my router. I can’t get to google for example.
When I traceroute to a device on subnetX from anywhere in the world it does make it to my aaa.bbb.188.164 router, but stops there. This tells me that my ISP is routing the subnet correctly, but my router does not know how to handle it even though both subnets are local to the interface.
I have done this plenty of times with Cisco, but can’t quite figure it out on Vy.
