Hi,
I installed and configured a NetBSD 2.0 Router. The Router has two Realtek
8129/8139 Network cards and he should assign IP-Addresses via DHCP. My problem is,
that my Clients donエt get a IP-Address from him. When I try to ping the router, I have
100% packet loss. 
The Internet connection via Kernel PPPoE is working properly. I
configured the second Network Card as the Internal Interface. 
Iエve created the file /etc/ifconfig.rtk1. 
Config example: inet 192.168.1.10 netmask 255.255.255.0 media autoselect
After booting the Network card comes up and is recognized properly and
marked as active.
For DHCP I used the following configuration: 
# Setting DHCPD global parameters
allow unknown-clients;
# Set parameters for the 192.168.0.0/24 subnet.
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.2 192.168.0.8; 
default-lease-time 604800; 
max-lease-time 604800; 
option subnet-mask 255.255.255.0; 
option domain-name-servers 1.2.3.4, 1.2.3.5; 
option domain-name "your.domain.name";
option routers 192.168.0.1; 
 
}
I used exactly the same example from the FAQエs. (Of course I have modified
it with my datas)
DHCPD is enabled in the /etc/rc.config. DHCPD_flags are set with
rtk1.(Internal Device)
My first guess was that the rtk1 NIC is defect. But sheエs not. I tested
the card in a other PC and she was working properly. 
Probably it is important to mention that I use PF as loadable Kernel
module. But anyway I should be able to ping the router. 
Iエm grateful for any help. If necessary, I will provide configuration
files or further details.
Regards
Carsten
