Hi All,
 
just want to confirm,
since active and passive FTP mode has slighty different operation ( http://slacksite.com/other/ftp.html ) , what would be the Reflexive ACL look like if i want to let active mode FTP to pass fa0/0 ?
 
=======================================
 
LET ACTIVE MODE ( and PASSIVE MODE inclusive ) to pass
 
int fa0/0
 ip access-group outgoing out
 ip access-group incoming in
!
ip access-list extended outgoing
 permit tcp any any reflect comeback
!
ip access-list extended incoming
 permit tcp any eq 20 any
 evaluate comeback
!
 
=======================================
=======================================
 
LET PASSIVE MODE ONLY
 
int fa0/0
 ip access-group outgoing out
 ip access-group incoming in
!
ip access-list extended outgoing permit tcp any any reflect comeback
!
ip access-list extended incoming
 evaluate comeback
!
 

====================================
 
is this ok ?
 
thanks.
