The topology may change, so it's better ping the closest roouter and to natting in it. > If this is not possible (and you are UDP pinging you firewall) open > dport 4000 udp in INPUT chain on your firewall and do natting: > > iptables -t filter -A INPUT -p udp -m udp -s 10.10.0.0/16 -d > 10.10.100.1 --dport 4000 -j ACCEPT > iptables -t nat -A PREROUTING -p udp -m udp -s 10.10.0.0/16 -d > 10.10.100.1 --dport 4000 -j DNAT --to-destination 192.168.1.2 > > This way 192.168.1.2 host should receive udp packets coming from the firewall. This is what I've done. But, packets are reaching INPUT chain, counters of the first rule are increasing, and packets are not reaching second rule, it's counters are zero all the time. And DNAT'ing not working :/ > My setup is running smoothly with UDP and NAT, I'm using with > playstation online games... > > Hope this help.
