Border routers ACL In rule Acl in permit tcp any host ***.***.***.**6 permit tcp any host ***.***.***.**5 permit tcp any host ***.***.***.**4 permit tcp any host ***.***.***.**3 deny ip any any log The firewall then filters on a port level. My question is if they are denying all IPs other that what is specified in the list is it necessary to then add the standard spoofing deny rules (ie drop localhost, mulicast, RFC1918 addresses etc)? This will be taken care of the deny ip any any rule would it not? --------------------------------------------------------------------------- Forum Systems PRESIDIO: PGP / XML GATEWAY APPLIANCE The Presidio integrates PGP data encryption and XML Web Services security to simplify the management and deployment of PGP and reduce overall PGP costs by up to 80%.
