My network have Exchange server working behind cisco router, I am going to install barracuda device behind the router to filter spam emails ( smtp traffic ).
the ACL I have is 2 ACL one for the outbound traffic and the other for the inbound traffic
as the following :
Exchange Public IP : 10.1.1.1
Exchnage Private IP : 192.168.1.1
ACL_Outbound
permit udp host 10.1.1.1 any eq domain
permit tcp host 10.1.1.1 any eq smtp
permit tcp host 10.1.1.1 any eq www
ACL_Inbound
permit tcp any host 10.1.1.1 eq smtp
permit tcp any host 10.1.1.1 eq www
permit tcp any host 10.1.1.1 eq 443
permit tcp any host 10.1.1.1 eq pop3
NATing
ip nat inside source static 192.168.1.1 10.1.1.1
That is all and is working fine, Now my question what I have to modify in the above settings so I can keep Exchange ( POP3 & OWA ) and Barracuda ( SMTP ) working together ??
Note I am going to assign the Barracuda this IPs:
Private IP : 192.168.1.2
Public IP : 10.1.1.2
