I have installed OpenWrt 17.01.6 on my old D-LINK DIR-600 rev.B2. Lan & Wifi are working correctly however when I try to connect the WAN port to my ISP router (a Huawei HG8045H) as a DHCP client it does not seem to be able to get an IP.
Here is my setup:
When I use it as a dhcp client, udhcpc seems to send requests and that's it : daemon.notice netifd: wan (1888): udhcpc: sending discover
When I use static IP, I can ping 192.168.100.1 but not 18.104.22.168 for example.
Any idea in what could be wrong ? I've even tried to put the IP in DMZ on my ISP router without success.
You are correct my bad, I already changed the IP to 192.168.100.10 but forgot to export the config again after. I managed to connect to the other router at 192.168.100.1 but not the internet :s I am gonna have a look at tcpdump then.
Yes correct, for the IP in fact it is 192.168.100.10 for my openwrt router and 192.168.100.1 being the isp router, I've fixed it earlier forgot to export the config again. I am gonna have a look to tcpdump then.
