Hello.
Can someone please tell me why I cannot access a machine inside my LAN from outside? These are my rules to try to accomplish that task:
$iptables -t nat -A PREROUTING -i $EXT_IFACE -p tcp \
-s $UNIVERSE --sport $UNPRIVPORTS -d $EXT_IP --dport 22 \
-j DNAT --to-destination 172.16.0.200:22
$iptables -A FORWARD -i $EXT_IFACE -o $LAN_IFACE -p tcp \
-s $UNIVERSE --sport $UNPRIVPORTS -d 172.16.0.200 --dport 22 \
-m state --state NEW -j ACCEPT
$iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
What am I doing wrong?
When I try to ssh from outside our network I can see it gets to the prerouting but, nothing gets forwared:
Chain PREROUTING (policy ACCEPT 1223 packets, 93798 bytes)
pkts bytes target prot opt in out source destination

Thanks in advanced for your help.
