Welcome to Cisco Support Community. We would love to have your feedback.
We have an internet connection from a pix 515e via a leased line router.
the users can access the internet no problem and also we can get people accessing our web server but we have no outbound or inbound email.
we have our own internal email server.
out internal email server is set to 192.168.1.3 and we have a static command in the pix to say
static (inside,outside) 126.96.36.199 192.168.1.3
(188.8.131.52 has been changed for security purposes)
so the real world address for out mail server is 184.108.40.206 and this is translated to 192.168.1.3 this does not work, no email at all.
but, we have a web server 220.127.116.11 real world address which gets translated to 192.168.1.11 and this works without any problems.
outbound internet is also working perfectly.
please see our config below.

Have a read of the following document and let me know if it helps or if you need further assistance:
Regards - Jay.
Thanks for the web link but this is nearly the same as what we have.
we have the static commands in and the access-lists required.
the nat (inside) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface
these 2 statements are need as we are associating everything that goes outbound to the internet to the outside interface as we can only use this address and the other outside address are taken up by www,mail and other servers.
can you please help.
static (inside,outside) tcp
access-list mail_in permit tcp any host
access-group mail_in in interface outside
Remember to execute command clear xlate after the modifications and save with command write memory.
Hope this sorts out your problem and let me know how you get on.
Forgot to add on my previous post, try adding the following command on the config:
> no fixup protocol smtp 25
Let me know your outcome.
can you ping the smtp box from the pix:
pix1# ping inside 192.168.1.3
1. what is the gateway set for the smtp server? (shld be inside IP of PIX)
2. can the www box telnet to port 25 on the smtp box?
3. can you ping from the smtp box to the inside interface of the pix?
4. If yes to the above then check your ACE in the ACL for smtp , is there any count on that is it increasing when you try to access it from the ouside in?
5. If not then you have an ACL issue somewhere maybe. use "debug icmp trace" on the pix w/o the "" and see where the packet is going.
This should point you in the right direction to solve the problem.
Did you solve this problem? I am having the same problem with my Mail server and PIX. Do you have to have a static (inside,outside) translation for your Mail server?
no this did not solve my problem and i am still having major issues.
The config has a static (inside,outside) translation but yet this is not working for my mail server.
have you the same issue as well and have you managed to get round this
Can you post your PIX config to me at email@example.com and please remember to change real IPs and passwords etc.
And did you try the no fixup smtp as I suggested earlier? make sure to clear translations with clear xlate after static or ACL modifications.
