I apologize, I made a couple mistakes in my response.  ACLs are not 
supported on E0 and E1 Gig/FE cards.  You used to be able to do them anyways, 
but they didn't work.  They were removed in recient releases.  They will 
be supported by (and re-enabled on) the Engine3 10 port GigE cards under 
development.

We found this out the hard way when we upgraded a pair of GSR with GigE 
"DMZ" type interfaces behind it.  We had to scramble to install a 7xxx 
series routers to serve as dedicated DMZ routers and do the ACLs on them.
