Dear All: I want to build a vpn server on one of my computer. Following is the details Client Name : client Client Tunnel Network Interface : ppp0 Client Tunnel Network Interface Address : 10.255.255.200 Server Name : server Server Tunnel Network Interface : ppp0 Server Tunnel Network Interface Address : 10.1.1.2 Server External Network Interface : eth1 Server External Network Interface Address : 210.34.14.211 Target External Network Interface Address : 210.34.4.20 I have get the correct ip "10.255.255.200" from the vpn server and can ping server's ip "10.1.1.2". As said in the website http://poptop.sourceforge.net/dox/redhat-howto.phtml "Once you can ping from the client to the server using the IP address assigned within the tunnel, you know it works". This means that I install vpn software successfully. "You may need to configure your server to forward the packets further, but that's a routing problem that has nothing specific to do with pptpd" However, I am not familiar with iptables. So I used the website http://poptop.sourceforge.net/dox/diagnose-forwarding.phtml?cn=client&ctni=ppp0&ctnia=10.255.255.200&sn=server&stni=ppp0&stnia=10.1.1.2&seni=eth0&senia=210.34.14.211&tenia=210.34.4.20 to diagnose the rule of iptables I have passed first four steps and failed in *Test 4* Can the server forward the requests to the target? The suggestion from the website is "The most common cause of failure for this test is /iptables/ FORWARD rules." How can I fix this problem? Best regards.
