I have no idea... but it is probably the reason it's not working. To verify, we need another device to test the theory. Thus the DD-WRT unit.
Well I realize that I can do more with the DD-WRT router software which is one reason I like the open source software, but I’m definitely going to need help with verifying the settings.
for DD-WRT, please visit the DD-WRT forums. That firmware is not at all related to OpenWrt and is not supported here.
I'm simply suggesting that you try DD-WRT instead of the Belkin device as a test, but help with DD-WRT is out of scope for this forum.
Well i just need to know some basic things cause it does give the options to set it as a gateway and a router.
Gateway is the same thing as a router.
Just reset the DD-WRT device to its default configuration. IIRC, the default subnet is 192.168.1.0/24 with active DHCP and DNS servers and it should have the wan configured as DHCP client. This should be compatible with your OpenWrt config.
Connect the wan port of the DD-WRT device to eth2 on your x86 box, and then connect another computer to one of the DD-WRT lan ports. Make sure the computer is configured to be a DHCP client and then test.
It’s been awhile and I’ve been doing some testing on the dd-wrt router labbing, my home network is my lab. I have wanted to make it communicate with my other networks. I have determined that with gateway mode on the dd-wrt it introduces NAT which hampers communication with the other devices.
So I changed it to Router mode and lost internet connection. So talking with AI to determine the problem which had me verify that I had a static route setup and verify the firewall saying it should be working, I discovered that while having the interface in the openwrt main network firewall zone that it wasn’t passing traffic to the second eth2 interface. So I created a separate zone for the second interface adjusted the firewall and then I had internet. I had similar issues to what I had with the Belkin N300 which I thought was a Bug in the Belkin getting DNS.
So I tried the the Belkin again with the same settings as I had before since I had not reset the device since changing to the DD-WRT router. Plugged into the wan interface WAN settings: WAN Ip[192.168.2.2] SNM[255.255.255.0] GW[192.168.2.1] and DNS[192.168.2.1]
LAN: IP[192.168.3.1] SNM[255.255.255.0] had internet as soon as PC connected. So I’m guessing the Belkin is just in router mode not gateway mode. Which is why I was having issues.
