Then you can on the new machine exec ping 4.4.4.4, for example, and you will see, if router can forward packet to the next hop correctly.
You can try to install tshark (or tcpdump or tethereal) utility even on the new host even on the routing machine and watch packets. On routing machine can be denied forwarding by iptables (try exec iptables -L -n and check rules in the FORWARD chain). If this machine is Linux, it has to have allow forwarding, try to see /etc/nf file. My CentOS 5.7 server can't access the internetĬan machine with IP address 192.168.137.1 forward traffic from network 192.168.137.0/24 to the internet?
