Guys,

I have configured a Dial-in server from a Redhat Fedora Core 3 linux. I have already configured an external serial modem and already included the linux port ttyS0 in the /etc/inittab file.

Also, I have turned on PPP dial-in service by modifying the /etc/mgetty+sendfax.login.config file and included AutoPPP.

Also, I have created entries in the /etc/ppp/options.server file and created entries shown below:

-detach
asyncmap 0
modem
crtscts
lock
proxyarp
ms-dns 192.168.2.230

Also, created the /etc/ppp/options.ttyS0 file with following entries:
192.168.2.230:192.168.2.40
netmask 255.255.255.0

and also created user entries in the /etc/ppp/pap-secrets file with corresponding map to Unix users.

Also, I have enabled routing from the dial-in server by modifying the /etc/sysctl.conf file and set the flag of ipv4_forward=1.

However, when I tried to connect a Windows 2000 professional workstation there was a successful connection which I have seen in the /var/log/messages file that there was succesfull login. I also ping the dial-in server IP address of 192.168.2.230 and there was a reply. However, when I tried to ping the e-mail server IP address (192.168.2.252), there's a request timed-out response. It seems that my dial-up client has established connection with the dial-in server only but not in the network.

Also, I have checked the IP configuration of the Windows 2000 professional client and it has a network subnet of 255.255.255.255. Does this caused the network routing or access problem? Is there anything I could do to my other configuration files for me access the other network servers via dial-up service?

Thanks.
