Can't connect gateway DHCP ADSL Modem after promote Windows 2008 DC

pietoe
I have a problem with my internet connection trough my ADSL Modem (gateway).
First we using ADSL modem(DHCP) to connect as a gateway to internet, we using windows 2000 DC for server. The connection is ok, our server and client can ping and browsing through gateway (192.168.1.77)
Then we've tried to develop using windows 2008 as a DC, but after domain create it the internet gateway can't access the internet gateway.

This is the configuration
DC Win 2000 = 192.168.1.12
Gt 192.168.1.77
DNS1 192.168.1.12
DNS2 202.x.x.x

DC win 2008 = ip 192.168.1.247/16
Gt 192.168.1.77
DNS1 192.168.1.247
DNS2 202.x.x.x

PC with ADSL Modem =
eth01 (LAN) not join domain
IP 192.168.1.77
Default G/W not set
Subnet Mask 255.255.255.0

eth02 (ADSL Modem) #DHCP 192.168.1.x - 254#
IP 192.168.1.6/24
Default Gateway 192.168.1.1
DHCP Server 192.168.1.1
DNS Servers 192.168.1.1

PC Client : ip 192.168.5.9/16
Gt 192.168.1.77
DNS1 192.168.1.247
DNS2 202.x.x.x

Before promote server to Domain 2008,PC Client and server can access gateway (internet) locally and can ping the gateway 192.168.1.77

But after promote server to windows 2008 domain the server and client can't ping the ip gateway 192.168.1.77, but can ping another DC (2000) and Clients.

Is it the problem cause by ADSL modem using DHCP? but before it, they using windows 2000 domain the ip gateway can ping the ADSL PC gateway and it's ok for internet.

Is there something with windows 2008 domain behaviour (firewall set turn off)?
