I am running Red Hat 7.1 and updated the kernel to 2.4.5. I have followed
all the configuration in the HOWTO.

My network is like this:
eth0: get the ip by DHCP via cable modem
eth1: connect to the LAN, ip = 192.168.0.1

My internal pc(win2000) can connect to the linux server(telnet, smb).
However, the internal pc can't ping anywhere outside the LAN except the ip
of eth0 by the DHCP. I have read the whole HOWTO and can't fix that.
Please help...

Here is the detailed info, hope can help fixing the problems.
