my desktop PC has 2 NICs.
Each NIC is connected to a dedicated router.
This means, my network has 2 routers.
Router A is provided by ISP, and desktop PC is connected to its LAN with network 192.168.1.0/24.
Router B is running Gargoyle, and on the downstream side there are 2 network segments: LAN (172.16.1.0/24) and DMZ (172.16.9.0/24).
Each network segment is setup on a dedicated NIC, means there's no VLAN.
The desktop PC is connected to LAN.
So, the bottom line is that desktop PC has 2 LAN connections; the relevant IPs are served by DHCP.
My main issue currently is that I cannot ping 172.16.9.1 that is router B's IP of DMZ, and consequently I cannot ping any other client in subnet 172.16.9.0/24.
Restriction is that DMZ must be only accessible from clients connected to LAN, subnet 172.16.1.0/24.
Can you please advise how to fix this issue?
Here's the route table:
Code: Select all
