Hi all recently, I set up a firewall like environment, where different ports of a linux server are forwarded to servers behind this machine. I don't have any problems with TCP packets. But I'm not able to get any UDP packets behind the linux port forwarder (the intended service was DNS). I used the following rules (besides others for TCP protocols): 10.0.0.1:/ # ipmasqadm portfw -l -n prot localaddr rediraddr lport rport pcnt pref UDP 10.0.0.1 192.168.1.3 53 53 8 10 TCP 10.0.0.1 192.168.1.3 53 53 10 10 Telnetting to 10.0.0.1 53, I get the connect as expected. Using nslookup www.xxx.ch 10.0.0.1, I don't get any response (just a timeout after some time). What did I do wrong? Does port forwarding nor work for UDP? Where can I find more vorbose information for port forwarding than with the -h option of ipmasqadm?
