I bought a Routerboard RB2011.
I plugged 2 computers to ETH6 & 7, connected the device’s ETH1 to my firewall’s LAN port, and plugged firewall’s WAN port to my Internet router, All the lights are green and they have an IP address. I also can successfully ping from device’s ETH1 to FW’s IP, but I can’t connect to the Internet.
However, if I use the Wireless connection (provided by the FW), I can connect to the Internet just fine.
Any ideas?
