Hi,
I'm new to ASA.
Need some help to config the ASA Firewall. I'll be installing an antispam in the DMZ and a new Mail Server in the Tusted. As such, need to forward port 25 from the External IP to the DMZ's AntiSpam IP plus to allow port 25 from DMZ to Internal.
Please advise on how I can do this.
Thanks & regards,

for inbound traffic from outside to dmz
static (dmz,outside) tcp
access-l outside_acl permit tcp any host
access-g outside_acl in interface outside
For communication between dmz and inside
static (inside,dmz)
private ip-->ip address of internal exchange server
access_list dmz_acl permit tcp any host

Thanks for the reply. Will try this.
By the way, we have a Active-Passive ASA cluster. By changing the above on the Active unit, will the change be automatically added to the Passive unit ?
