I have a home network based on the following:
Netgear ADSL Router at 192.168.2.1 This is defaul gateway and manages DHCP from 192.168.2.2 to 192.168.2.100 the Router is connected to a switch. An ethernet cable runs from this switch to another switch in another room where I have appliances who get DHCP addresses from the Netgear.
I want to add wifi connection into this other room. I have an unused TP-LINK router, of the type with no-DSL port, just 4 ethernet LAN ports, 1 wireless interface and 1 ethernet port named WAN.
The TP-LINK setup is apparently easy. I connected the WAN port to the switch. I configured the WAN interface such as:
IP address: 192.168.2.101 (part of my main network) Subnet mask: 255.255.255.0 DNS: 192.168.2.1 (the router actually connected to the network)
The LAN setup must be different so I decided for:
IP address: 192.168.3.101 DHCP on (from 192.168.3.10 to 192.168.3.20) Subnet mask: 255.255.255.0 DNS: 192.168.2.1 (the router actually conncted to the network)
It works, that is I can access the internet from wifi devices connected through the TP-LINK. But I cannot access the configuration setup from any device in network 192.168.2.X and I cannot figure why.
I tried port routing from 192.168.2.101 to 192.168.3.1 but without success.
In the meantime I changed the way, linking the switch to one of the LAN ports of the TP-LINK and disabling DHCP. In this case the TP-LINK acts as a wireless bridge and everything works. But still I do not understand what is it wrong with the routed setup where I cannot access the device.
Can anybody help me understanding what is wrong?
