Need to access OWA or ping the mail server from the guest wireless network

Dear experts

I am challenge here on how to configure this. I wonder what are the steps to take for the  guest wireless network to ping the mail server only.

We want to be able to access OWA over the web and is not possible.

You can view my config.

interface Ethernet0/2
 description Guest Internet Access
 nameif Guest_Internet
 security-level 50
 ip address 192.168.100.1 255.255.255.0

dhcpd address 192.168.100.50-192.168.100.254 Guest_Internet
dhcpd dns 4.2.2.3 4.2.2.2 interface Guest_Internet
dhcpd lease 28800 interface Guest_Internet
dhcpd enable Guest_Internet





Thanks!  is-okc-asa-01

Looks like you have no ACL applied inbound on the DMZ interface.  Since the inside interface is considered more secure, you will need to add an ACL to permit desired traffic from the DMZ segment to the mail server IP address.  If all they need is OWA, then that should be only TCP/443.  You shouldn't need to deal with NAT issues between the interfaces, but it's something to keep in mind.  

access-list in-dmz permit tcp any host 172.16.8.221 eq 443
access-group in-dmz in interface Guest_Internet

I don't have a in-dmz" in the firewall. Do I just enter the lines you gave me?

You will also have a problem with DNS, you are using internet srevers.  You will need to use something that can hand you the local IP of the server.

Without it you are getting your public IP address, and that doesnt work out so well.
