I am an IT administrator for Fully Microsoft based Network , Internet , Email and every thing work fine.
The next plan is to install PIX Firewall in front of ISA.
I am new to Cisco PIX , so I need full configuration to setup the PIX 506E. either using command line or PDM web Interface.
What I need excatly to do , is firstly allow Internet connection , secondaly , forward any SMTP Traffic to ISA Server because I am publishing the Exchange Server through ISA.
