Hello, For ascii art fans: INTERNET----[eth0 LINUX1 eth1]----[eth0 LINUX2 eth1]----[Windows] Linux1 eth0 - public address, NAT, eth1 - 10.0.2.1 Linux2 eth0 - 10.0.2.2, NAT, eth1 - 10.0.5.1 Windows - 10.0.5.13 What I can do on Linux1 and Linux2 to allow connect from INTERNET to telnet on Windows machine? I put on Linux1 something like this: iptables -A PREROUTING -t nat -p tcp -d (public address) --dport 23 -j DNAT --to 10.0.2.2:23 On Linux2: iptables -A PREROUTING -t nat -p tcp -d 10.0.2.2 --dport 23 -j DNAT --to 10.0.5.13 But it still not working :( What I doing wrong? Adi
