Hi,
I just setup a dialin server on RedHat 9.
Dial in server is a member of LAN with common gateway 192.168.1.1.
I can browse internet from dial-in server and I can ping any other PC in the LAN.
From a windows PC i can dial in and connect to the server but I cannot browse Internet.
When connected to the dial-in server my windows PC has the following ipsettings and I cannot ping
any other PC in the LAN except dial in server (192.168.1.10) I'm connected to:
c:\>ipconfig /all
PPP adapter test2PPP:

As you see the IP and the gateway for my windows PC are the same - 192.168.1.171. Is this correct?
My guess is that the linux Dial-in server doesn't route/forward packets from PPP to the rest of the LAN?
How I can prove if it's true or not?
Which config files/log files to be check out?
Which tools I can use to debug it?
Thank you for the help in advance! Milen ================================== Please see some of config files bellow: 1. /etc/sysctl.conf contains the line: -------------------------- net.ipv4.ip_forward = 1 -------------------------- so cat /proc/sys/net/ip4fw/ip_forward shows "1"
/etc/ppp/options contains: ----------------------- -detach asyncmap 0 netmask 255.255.255.0 proxyarp lock crtscts modem noauth ms-dns 192.168.1.1 ms-dns 192.168.1.1 ---------------------
/etc/ppp/options.ttyS0 contains: ----------------------- 192.168.1.10:192.168.1.171 -----------------------
I *THINK* you need to specify 'defaultroute' in your /etc/ppp/options file to allow the ppp connection to change the computers default route to run through your modem ppp connection.
check what 'route -n' gives you while you're connected.
