Hi,I'm trying to NAT this protocols: HTTPS, FTP (active and passive), NTP, SSH, SMTP, POP3, POP3S, IMAP and IMAPS. But I'm not sure if I'm doing it right.
# This is my network config: # Internal network: 192.168.0.0/24 # External IP: 193.135.345.123# NAT for HTTPS, FTP (active and passive), SSH, SMTP, POP3, POP3S, IMAP and IMAPS. iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -p tcp -m multiport --dports 443,21,20,22,25,110,995,143,993 -j SNAT --to-source 193.135.345.123
# NAT for NTP.iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -p upd -m multiport --dports 123 -j SNAT --to-source 193.135.345.123
I have also loaded these modules: modprobe ip_conntrack modprobe ip_conntrack_ftp modprobe ip_nat_ftp Thanks, Patrício Batista Portugal.
