hi, I have instaled the DHCP as per (http://www.howtoforge.com/dhcp_server_linux_debian_sarge), but other computers can not access the internet, nither can ping any ip. They getting the ip address from DHCP. I can do ssh to the box that instaled DHCP(192.168.1.100) from my lan. I also notice i cannot ping to default gatway 192.168.1.1 from 192.168.1.100 box. if i do route: *.myispdnsaddress * 255.255.255.255 ppp0 192.168.1.0 * 255.255.255.0 eth0 default * 0.0.0.0 ppp0 also i have added the default ppp0 manuly. Normaly default comes to eth0 with 192.168.1.1 I have two NIC on that box other one is disabled. I'm using same switch to connect ADSL and other computer is also connected to that switch. switch -> ppp0 switch -> eth0 switch -> LAN Do i need to use 2nd NIC to connect the switch for LAN? like: eth0 -> ppp0 switch -> eth1 switch -> LAN Thanks Bip
