I have a Mail Server behind Firewall. With an ipcop firewall connected and port 25 forwarded to the mail server ip, the exchange server works perfectly.
Now I have a combination of Cisco router and PIX. I cannot seem to be able to configure the pix and router to allow smtp traffic to the mail server. HELP!
Internet -->Cisco 3700 --> Pix 515E --> Mail Server
What do I do to get the router and the pix to forward port 25 to the Mail Server.
