We have a Cisco Pix Firewall v 6.1(4) that is fully configured and operational. E-mail comes in and goes to our Exchange server (10.156.0.30) Http requests come in and go to Exchange also for Outlook Web Access. We purchased a Barracuda spam firewall (10.156.0.113) and are trying to change the internal ip that smtp goes to while leaving Http requests as is.
I have tried various settings and cannot get this to work. Here are some of the lines from the original configuration.
access-list acl_inbound permit tcp any host 22.214.171.124 eq smtp
access-list acl_inbound permit tcp any host 126.96.36.199 eq http
alias (inside) 10.156.0.30 188.8.131.52 255.255.255.255
static (inside,outside) 184.108.40.206 10.156.0.30 netmask 255.255.255.255 0 0
I removed the alias and static lines and added this line:
static (inside,outside) tcp 220.127.116.11 smtp 10.156.0.113 smtp netmask 255.255.255.255 0 0
I saved the configuration (I think?) "write terminal" and then "write memory" yet mail still goes to 10.156.0.30
Nowhere in the config does 10.156.0.30 show up yet somehow the smtp packets still go there. How do I fix this to do what I want?
Thanks for the help.
