hi, i recently set up ip masquerading, so im usign my Redhat 7.1 linux box as my router. I have an internal box running a service that i need to make available to the
outside. the port is 5500 and the internal ip of the box is 192.168.0.11,
heres what i tried:
# iptables -t nat -A PREROUTING -i ppp0 -p tcp --dport 5500 \
********-j DNAT --to-dest 192.168.0.11
it goes through without any errors, but when i try to connect to the service
usign my external ip *it says Host Refused connection. i also tried port
scanning for this port, and it doesnt find it.

Please help me solve this ASAP.
Thank you in advance,
