Hi!
i have a problem, i don´t know how to resolve it.
On ISA Server 2004 has 3 nics with the following configuration:
Internal:
Ip: 192.168.1.9 Gw:null dns:192.168.1.5
External (this nic has a IP Private):
IP:172.17.1.15 GW:172.17.1.1 DNS1:10.0.104.135
DMZ:
IP:172.27.1.15 GW:NULL DNS:NULL
On DMZ segment i have a host configured how to a web server,smtp relay and public DNS (authoritative for my domain). This host is not operative and has the following configuration:
IP:172.27.1.16 GW:172.27.1.15 (NIC DMZ ISA SERVER) DNS:172.27.1.15

My ISP natting the IP External 172.17.1.15 (static address private of ISA Server) for turn it on 200.52.208.133 (public address).

Same way, my ISP have configured the IP External 172.17.1.20 for turn it on 200.52.208.42, with this static address IP I had configured the services www,smtp relay and dns. Now, for create to DMZ segment the IP configuration for this server change to: 172.27.1.16, this IP is not known for the router of my ISP and consequently don´t out to Internet. Too, the querys incoming of Internet at arrive to the router, not will found the server (www,smtp,dns) with the static address IP expected.

How do i can resolve this detail?
Thanks
