I need some help getting my Exchange Server to be able to send out emails.  Can someone review my Pix config and verify that the setting are correct so I can elminate the Pix from the problem?

Here you go:

static (inside,outside) tcp interface smtp 192.168.2.22 smtp netmask 255.255.255.255

You should be able to send email out base on the configuration of the PIX.

I also assume that the following is configured but not used and all traffic is being routed via PIX inside interface:

interface Ethernet2

  nameif exchange

security-level 100

ip address 10.0.30.1 255.255.255.248

I assume that routing is correct on the PIX, ie: for 192.168.2.0/24 network on the PIX is being routed towards 10.0.20.3 (you can check on the PIX using "show route"

Ok, it kinda works, but I can't rehecieve emails from outside the internet.  Can you review the config and verify the problem is not with the Pix?  Do I need to configure a route on the 3745 router too?

ISP IP Address: 24.234.xxx.xxx

PIX IP: 10.0.20.1 (inside)

3745 Router: 10.0.20.3 F0/0       192.168.2.1 F0/1

no static (inside,outside) tcp 192.168.2.22 smtp 24.234.xxx.xxx smtp netmask 255.255.255.255

access-list outside-acl permit tcp any host 24.234.xxx.xxx eq 25

access-group outside-acl in interface outside

While trying to input the new confige i get this:

ERROR: Static PAT using the interface requires the use of the 'interface' keyword instead of the interface IP address

any ideas

Here you go:

static (inside,outside) tcp interface smtp 192.168.2.22 smtp netmask 255.255.255.255

thank you so so so so so so so so so much....three days of pulling my hair out and it works finally....
