Hi there,
i've some problems to configure my lan clients to access the internet
through the internal firewall.
The scenario is described below:

i've configured a first Isa Server 2000 firewall with 3 nics, two
connected with two separate internal lans and one connected with DMZ
segment (with some servers)

10.16.2.1 -->Internal NIC1 
                           192.168.10.1 DMZ NIC                    
10.16.3.1 -->Internal NIC2

on DMZ i've some servers configured with 192.168.10.x address family and a
second firewall configured with two NICs:

192.168.10.9 --> DMZ NIC   

xxx.yyy.zzz.kkk ---> Internet NIC

i've configured servers on DMZ to access the internet and published some
of them (WEB,MAIL etc.) and all works fine.
But i can't get access the internet from internal LANs.
In which way i've to configure the internal firewall to access both the
internet and dmz servers?
Help would be appreciated.
Thanks.
