PIX Issue

Unanswered Question
Mar 17th, 2007

Hell All,


I have mail server running behind the PIX Firewall, i fount that mail server is running well inside the network, but while sending mail from GMAIL ot YAHOO or any other mail server to my mail server, its dosent work. and our mail server isnt log any thing process too. But still i can send mails from my mail server to any other mail server.


My question is,

1)is there any configuration required except NAT forwarding for port number 25, 110 for SMTP and POP3.


2)do i need to allow all the network for SMTP as incoming traffic...?


Thanks,

Dhaval Tandel

Hi,

If you could post your configuration, it would be helpful to diagnose any problems in the config.


To allow incoming mails to your mail domain from external world, yes you need to allow incoming access to the SMTP port of your server from "Any".

Check your ACLs..


Hope this helps.

Hi,


if you are using your MX Record at ur Service Provider then u don't need to open any port from outside to Inside , But if your MX Record is Hosted Direct to ur server then u need to open SMTP Port for Outside To Inside Access.


like

Access-list acl_out permit tcp host any host IP Address(urExchangeServer NAT IP) eq SMTP



Thanx
