i currently have a linux machine acting as my router/server, i have
put together a file of commands to run if i ever need to reply the
iptable rules

#flush the tables
   iptables --flush
   iptables --table nat --flush
   iptables --delete-chain
   iptables --table nat --delete-chain

   # Set up IP FORWARDing and Masquerading
   iptables --table nat --append POSTROUTING --out-interface eth0 -j
MASQUERADE
   iptables --append FORWARD --in-interface eth1 -j ACCEPT

echo 1 > /proc/sys/net/ipv4/ip_forward

# Allow loopback access. This rule must come before the rules denying
port access!!
iptables -A INPUT -i lo -p all -j ACCEPT
iptables -A OUTPUT -o lo -p all -j ACCEPT

iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 2049 -j DROP
iptables -A INPUT -p udp -s 0/0 -d 0/0 --dport 2049 -j DROP
iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 6000:6009 -j DROP
iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 7100 -j DROP
iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 515 -j DROP
iptables -A INPUT -p udp -s 0/0 -d 0/0 --dport 515 -j DROP
iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 111 -j DROP
iptables -A INPUT -p udp -s 0/0 -d 0/0 --dport 111 -j DROP
iptables -A INPUT -p all -s localhost -i eth0 -j DROP

#setup portforwarding
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 222 -j DNAT --to
192.168.0.2:22

everything works except for the portfowarding. im tryin to allow
access via ssh to a machine within the internal network. The problem
is when i connect from outside, it hangs, it does not refuse the
connection, it just hangs there tryin to connect. It seems to work
half-way but not completely, am i missing something?
