proxy-arp is not the feature Niels is referring to - i.e. proxy-arp is 
not quite the same as local-proxy-arp. You need something that supports a 
shared IP interface and a local-proxy-arp style mechanism to do this. 
An ERX-310 for instance will work nicely for your type of setup. The 
M-series are pretty flexible all-round boxes but they are (currently) not 
really suited for BRAS-type setups, which the E-series do very well.
