Hi all, I am using an FTP Server behind NAT (vsftpd v1.2.0-5 on Fedora Core 1 kernel 2.4.22-1.2115.nptl). The server is behind NAT router (Zyxel Prestige 660R-61). I have problems connecting to it from a computer outside. I am looking for a way to solve this at FTP Server side. I have enabled DynDNS and port forwarding for the needed port ranges (20:21, 7727:7777) on the ADSL router. But I cannot connect from the outside. Please, somebody, tell me how can I troubleshoot the problem. (where do i look for 'syslog' ?). Or, even better, do you guys see any solution for this ? Thx in advance /ganick PS: My cofiguration is as follows: ** iptables rules ** ... -A RH-Firewall-1-INPUT -p udp -m udp --dport 20 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 7727:7777 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 20 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 7727:7777 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 21 -j ACCEPT ...
