Hi,
I'm setting up a new network where I´ll have webhosting servers behind the PIX.
I get problems with the DNS, because when the servers that are behind the
firewall ask about any record the DNSs respond with the public IP, and when it
try to connect, It can´t. About it I can't send an email from MAIL1 to MAIL2.
I was reading about the alias command, but it appears to be used when you have
the DNSs outside your network.
Anybody knows how I can resolve it?
Below is a basic configuration of my pix and the diagram of the network.
Thanks,
Charly
