Getting following error 'ping bad address 'lade-project.org'/ TP-Link WDR4300

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello

I have been able to install LEDE in my TP-Link WDR4300, and I am able to log on into the WDR4300. However, when I go to diagnostics. Network Utilities and ping 'lade-project.org' I have following error: 'ping bad address 'lade-project.org'

My WDR4300 WAN port is connected to a LAN port of my main router. I can see under 'Status Overview" that an IP address is assigned to WDR430, and I can ping from WDR4300 way up to the main router.

Have anyone seen this error? or Can anyone point me to the right direction?

Cheers

Sanity check: does your typo of "lade-project" have anything to do with it?

hey everyone,

OK I was wondering if a possible issue is the following:

  • WDR4300 WAN port is connected to LAN port of main router
  • Both WDR4300 and main router are on 192.168.1.1. IP address
  • HOWEVER. Main router assigned following IP address to WDR4300
    IPv4: 192.168.1.5
    Protocol: DHCP Client

Digging a bit more..
*Type: DHCP
*Address:192.168.1.5
*Gateway: 192.168.1.1 (which is same IP as main router)
*DNS1 and DNS2, same IP address as Gateway

Bottom line...I am not 100% sure if LEDE router and main router same IP address is the reason for my issue...any suggestions??

Cheers

You have two options:

  1. double NAT: put your WDR4300 lan ip address as 192.168.2.1, and let it handle 192.168.2.0/24. In this mode client connected to WDR4300 get ip address from 192.168.2.2 - 192.168.2.254. Gateway is 192.168.2.1 and there will be two NAT one from wdr4300 one from your main router.
  2. bridge: Bridge wan and lan together. Set a static ip adress on your wan port, give it something outside of the range of main router dhcp address range. Client connected to wdr4300 will be assigned ip address in 192.168.2.0/24 from the main router directy. Gateway remains 192.168.1.1 and only single nat.

hey mate,

Thank you so much for your options. Try number one, and yep, all good now, can ping my "lede-project.org". so Would you mind to explain what was the issue?

You cannot have two machines with the same IP (192.168.1.1) address in your network, and you cannot have two networks with the same range (192.168.1.x) on different interfaces of the same device (unless you have a very special use case, and really know what you are doing).

Hello Eduardo,

Thank you for your reply. I knew about the same IP address (so one unique IP address in same network per device). However,

you cannot have two networks with the same range (192.168.1.x) on different interfaces of the same device

did not strike me as an issue, I will get back to pen and paper and try to understand this one better....

Again thank you for your observations

Cheers

Your LEDE device was 192.168.1.5 on the WAN interface, and 192.168.1.1 on the LAN interface (let's forget that there was another 192.168.1.1 device on the WAN part). Now, when your LEDE device needs to contact another device, say 192.166.1.25, what interface should it use to send the packets? Both networks are supposed to hold all devices in the range 192.168.1.x.
