I have a very simple setup: AX3000 router ->(Ethernet "internet" WAN port) ->Arris SB8200 modem (Ethernet port)->Comcast Cable
LAN Address: 192.168.50.x (router @ 192.168.50.254
Modem address (fixed by mfg): 192.168.100.1
I would think that the modem's web server (192.168.100.1) should not be accessible from my LAN (192.168.50.x), but it is. Question is why (the router's internet port is plugged directly into the modem's Ethernet port).
No entries exist in either my laptop or router routing tables.
The arp cache on my lap top will show a successful connection for a time, but that's expected after making a successful connection.
Questions:
1. Why would the AX3000 allow (route) a connection from 192.168.50.x through it's internet (WAN) port to the modem's Ethernet port @ 192.168.100.1 ? (There are two Ethernet ports available on the modem.)
2. What layer is the connection occurring at (link layer???)
3. Should this condition be happening and is it a security risk?
Thank you.
