Transparent bridging wireless network

Hello,

I'm setting up a wireless network I wish to have branched off a Cisco 2620 router (w/ 1 FastEth & 1 Eth) and wish to use transparent bridging for the wireless modems, for the hosts behind them to access the Internet. I have a class C (ie. 5.6.7.x/24) that I wish to use for hosts behind the wireless modems, and wish to use 10.40.x.x for the wireless modems over Eth1/0. FastEth0/0 is on another subnet (and physical network) which is connected to the Internet - i.e. 1.2.3.4. Right now from a wireless modem (10.40.1.1) I can ping 10.40.x.x without trouble.. But can't pass any data to anything on the 1.2.3.x network or anywhere past that... I need the 10.40.x.x network and hosts behind it that are bridged, to be able to use the Internet. Here's my (slightly adjusted) configuration, care to examine?

--config start--

--config end--

Hmm... I'm not sure if I need the 'bridge' statements. Anyone?
