Wireless Bridge does not allow access to computers on the same network

My primary router is on tomato, and since I've been liking it so much, I decided to load tomato on my wireless bridge. After doing so, I followed these instructions (Wireless Ethernet bridge mode) to it to connect to the primary router. It was way easier than doing so on DD-WRT, and access to the internet works. However, access to computers connected to the primary router did not work. I believe this is a known issue (read comments in the link).

Guess tomato works well as a primary router but not so for a client router.
