My firewall is setup with cbac on lan to public interface and acls inbound from public to lan. When cisco VPN clients connect outbound they authenticate and register fine but only when a permit IP acl from secure host allows me to route. when testing I created udp and tcp range acls to match to get some idea of where packets were coming from however no matches. Can anyone suggest how I can limit inbound ipsec rather than allow ip permit?
