However the DHCP-server of your Omnia is distributing ip-addresses to the devices connected to it in the same range 192.168.1.x. You should at least choose another range for the DHCP-server of your Omnia, for example 10.0.0.x.
Has the modem a DMZ lan the Omnia could connect too?
And run a traceroute, either from the desktop or the omnia to see where it is getting deadended.
For example, if employees are restricted from accessing the internet but need to provide off-network support, using one port for your internal private network and another for the public internet allows users worldwide to access systems without breaching your network security policies.
NIC teaming combines your system's physical network interface controllers (NICs) into a single logical interface. One of the NICs is used to carry all network traffic.
However the DHCP-server of your Omnia is distributing ip-addresses to the devices connected to it in the same range 192.168.1.x. So to access your modem-router you go to 192.168.1.1 and to access your omnia you go to 192.168.1.1?
Dhcp Not Assigning Ip Address
If that is the case I think that is also the problem. @Big_boss: The modem assigns the Omnia address 192.168.1.5, i.e.In this scenario, packet loss occurs with packets originating from the IP on the NIC that does not have the default gateway.Consider the following example configuration: Given this configuration, traffic from both NICs are sent to the default gateway (192.168.1.1) regardless of which NIC received traffic.I can see the same address from my desktop on Luci’s status page in the Omnia, so I’m pretty sure that the modem assigns address 192.168.1.5 to the Omnia. As mentioned above the WAN LED on the Omnia blinks constantly as does the LED at the modem’s Ethernet port. If I disconnect the Omnia from the modem and use the same cable to connect my desktop directly to the modem I also have access to the internet, i.e. I also tried swapping ports and cables as well as reboots, but without success.From my desktop I cannot access any other web page or ping 184.108.40.206, from my laptop yes. Is there perhaps a firewall on the modem blocking Omnia from accessing the inet?Is there a better way to do it than modifying /etc/network/interfaces?Twice 192.168.1.1 on the network will cause trouble and might be the culprit here.Router IP Address in case someone is looking for it) so that both routers serve different subnets and IPv4 communication works now. I’ll investigate a bit further, but basic functionality seems to be working now. In the connection test IPv4 connectivity and IPv4 gateway connectivity are okay, IPv6 connectivity and IPv6 gateway connectivity fail (currently I don’t care too much as everything here is on IPv4). On the other hand on the Omnia’s hardware the WAN interface activity connector is blinking constantly. From my laptop I can connect to the modem under IP address 192.168.1.1 and from my desktop under the same IP address to the Omnia.As soon as I power up the Omnia I seen in the modem’s DHCP page that it assigns an IP address (192.168.1.5) to the Omnia.
