No, its disabled by default since most deeply embedded systems are not
gateways. 

To enable it you need to set the global variable ipforwarding to true.
There are a number of ways you can do this, eg simply set it to 1, or
use the sysctrl interface to set it. 

You will also need some way to setup the routes. There is currently no
routing daemon available for eCos, so you either have to use static
routers, or do some porting work.
