Hello, I've set up the network as follow:
Laptop A connects to the router board 133c with cable. Laptop B connects to another router with cable. (just normal router purchased at retail store). The two routers are connected wirelessly.
I run wireshark to keep track of the traffic and I discovered the following: when I ping laptop B from laptop A, an ARP packet was sent to laptop B and laptop B replied with its IP address, however, this reply couldn't get back to laptop A. I tried to ping laptop A from laptop B also, but same thing happened. It seems to me that the traffic can only go one way. Does anybody know how to fix this? I only setup a bridge to connect the ethan1 and wlan1 of the routerboard. Is this all I need? If not, what did I missed? Please advice.
Thank you very much.
