Connect to server from behind firewall

[lorandsm]

Hi,

I’m trying to connect to the NoMachine server using port 80. The NoMachine server is installed on my router (I configured a PC as a router). I’m trying to connect to it from a place which is behind a firewall.

I’ve configured the my firewall to redirect port 80 to 4000:

iptables -t nat -A PREROUTING -i $INET_IFACE -p tcp –dport $HOST_HTTP_PORT -j REDIRECT –to-port $HOST_NOMACHINE_PORT

iptables -t nat -A PREROUTING -i $INET_IFACE -p udp –dport $HOST_HTTP_PORT -j REDIRECT –to-port $HOST_NOMACHINE_PORT

where HOST_HTTP_PORT is 80 and HOST_NOMACHINE_PORT is 4000.

In server.cfg I left

NXPort 4000

I’ve tried with and without the following:

EnableUPnp NX

NXUPnPPort 80

But I couldn’t connect either way. Is there anything else I need to configure? Thanks.

Hello
We tried to reproduce the problem in our laboratory.Unfortunately we were unable to.

Please run the command “iptables -t nat -A PREROUTING” and paste the lines at the forum which is the end of 4000.

Is the computer where NoMachine installed connected to another router or modem?

If so please give the name and model.
