Firewall Wizards: Re: accessing SMTP server via the translated address

Re: accessing SMTP server via the translated address

Since your workstation is on the same internal subnet as the mail
server why would you try to ping out to the xlated ip? If your on the
same internal subnet you should be pinging the 10.10.1.2 ip. I guess
I am missing something?
