Message-Id: <406DD9F3.6060901@ansco.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ppp@vger.kernel.org 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: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface Physical Address. . . . . . . . . : 00-53-45-00-00-00 DHCP Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.1.171 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 192.168.1.171 DNS Servers . . . . . . . . . . . : 192.168.1.2 192.168.1.3 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 -----------------------
