All:
We run IMail within a university environment. Even though we do have the student network separated from our production network with VLANs, we still have the joy of dealing with attacks directed towards our IMail box from the student VLAN and computing labs. Thus, we get to deal with script kiddies from both the inside and outside. I�d like to place a transparent firewall device (Netscreen 5Xp) right in front of the IMail server. Since this configuration would result in a firewall inside our Windows AD network, I really need to make sure not only IMail traffic can pass in and out of the firewall but Window�ish stuff as well (MS Directory services, Global Catalog, WTS, etc) or the box won�t be able to communicate with the rest of the windows network. BTW � all other DCs use internal IPs so they don�t get hit with port scans, etc from the outside world. Has anyone else done this? If so, I�d hate to reinvent the wheel! What ports, protocols and directions did you configure on the firewall to protect the IMail box, as well as, the role the machine must play in the Active Directory infrastructure? Thanks!
