Cisco Zone-Based Policy Firewall


Customer complain HTTPS dosen't work
 
show policy-map type inspect zone-pair 
 
you did not see drop outbound but seeing drop inbound
 
class-map type inspect match-all https-class
 match protocol https
!
policy-map type inspect outside-to-inside
 class type inspect https-class
  pass 


!


policy-map type inspect inside-to-outside
 class type inspect https-class
  pass 


This might due to "match protocol https" can not match the return traffic, 
the work around is to map https traffic with access list
 
access-list https extend permit tcp any eq 443 any gt 1024
class-map type inspect match-all https-class
 match access-group https
