I have one realy big problem with PPPoE termination on 7600ES20+ module. I tried configure ISG on 7600 with L4 ACL ( for example block email port ) for PPPoE subscriebers on IOS
but L4 ACL on Virtual-template doesn't work!!! There is no any hits on ACL either subscriebers got regulary ACL through ISG service.
L3 ACL works OK (for example block ICMP traffic).
I can't beleive this!!!
