I am trying to port forward on tcp port 110 but I keep getting 
"telnet: Unable to connect to remote host: Connection refused" 


backround information:
localhost 192.168.1.1
email server 192.168.1.2


I get connection refused when I try any of the following commands

telnet localhost 110
telnet 192.168.1.1 110 

The only one that works is telnet 192.168.1.2 110


The command to configure port forwarding:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 110 -j
DNAT --to-destination 192.168.1.2





The output from iptagbles -L -t -nat 

DNAT       tcp  --  anywhere             anywhere           tcp dpt:pop3
to:192.168.1.2 


I have also looked at tcpdump but there are no headers that come across
the interface when I get an access denied, so it seems the kernel might
be stopping it before it gets on the wire.
