Ok. There shouldn't be any issues with this setup.
How are your clients and the ASUS media bridge AP set up? Using static IP address or getting DHCP from your modem/router?
What local IP addresses are used in your DHCP pool? 192.168.1.xxx xxx=2-? or 100-200 for example?
- On the D-Link router, turn off DHCP and statically assign the LAN IP (under Network) 192.168.1.2 (make sure this is outside the DHCP pool) with subnet mask 255.255.255.0. Once the router reboots with its new IP address, you must use that to access the web UI.
- Only connect to the LAN ports. WAN/Internet port will not work.
Your clients should receive DHCP requests from your modem/router unless you statically assigned them.
Modem Router is 192.168.1.1 and dhcp pool is 192.168.1.2-254. Other than that i have some binding rules to assign specific address to the devices based on their mac. Like i have 1.2 to a NAS device 1.10 to the Asus AP 1.100 to my mobile etc. It doesnt matter, everything works as it should in that manner. DHCP/DNS/Upnp and rest functions are disabled on the dlink and the asus that i want to only act as AP.
The problem comes when i assign a static ip on the dlink where i can no longer use the wan port. I have tried giving it the 192.168.1.99 and 1.254. It works and i can then find it on that address, but when i connect my adsl modem/router to the lan port (instead of the wan) i dont have internet access.
So to recap:
I leave it at 192.168.0.1 factory ip, connect modem/router to wan of dlink, i have internet, but cant access rest of network shares and resources.
I give it 192.168.1.x i get network access but not internet from router that is now connected in one of the lan ports. If i now connect router to the wan of the dlink it breaks off completely and needs a factory reset.
EPILOGUE.
HAVE DISABLED DHCP. HAVE DISABLED UPNP. THERE IS NO DOUBLE-TRIPLE NATING. ROUTING IS ONLY DONE WITH THE MODEM. IP RULES ARE ALL PROPERLY CONFIGED. CANT GET INTERNET FROM MODEM TO THE DLINK WITH LAN PORT AND 192.168.1.X TOPOLOGY.
