Ok heres my current setup
Cable modem -> WAN port of Router1 (it is the DHCP server)
all devices and dumb switch (and devices attached to it) connected to the ethernet port (or wireless) of Router1 works fine and can go online and talk to each other.
now from Router1/ethernetport 4 I connect to the WAN port of Router2. (router2 have DCHP enabled also)
now I connect a desktop / laptop to etherenet port of Router2. They get no internet access but can still ping each other.
Is there any setting I should do to Router1 or Router 2 to get devices connected to router2 to have internet access?
ohh router1 is a DD-WRT router and router 2 is a cisco small business router
BEFORE YOU SAY IT: I can.
1) just add a dumb or managed switched to the etherent port of Router1 to add more devices
2) disable DHCP of router2 and do Router2/Ethernet <-> Router1/Ethernet. in essence using router2 like a switch/bridge
The reason I am not using those two method is I want more security and total isolation of devices on router2 from being access by crap on router1.
You may say I can just use VLAN to isolate the two networks with the above method. but that is just not taking advantage of the security features of router2 also...
let say router1 or devices attached to it is compromised, the hacker will have to tackle another layer to get to the devices behind router2.
Do you guys have any comment or suggestion? I'm just working with what I have and don't want to put like a bunch more $$ on security apliances .
