I have chain of three machines. 192.168.42.2 is connected by an ethernet link to the middle machine 10.0.0.1 which is connected in turn to a dialup internet connection through ppp0.
From machine 10.0.0.1 I can ping machine 192.168.42.2 and the IP server 195.92.65.96.
From machine 192.168.42.2 I can ping machine 1.0.0.1, but not the server 195.92.65.96.
Running /sbin/route on machine 10.0.0.1 yields the following: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.42.2 0.0.0.0 255.255.255.255 UH 0 0 0 eth1 195.92.65.96 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 0.0.0.0 195.92.65.96 0.0.0.0 UG 0 0 0 ppp0 The first line is set by an entry in /etc/sysconfig/network/route. The value for /proc/sys/net/ipv4/ip_forward is 1 There is no firewall and the output from iptables -L is: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination What must I do to enable me to ping the IP server from machine 192.168.42.2 ?
