Networking :: Telnet Is Not Working With Iptables?

i want to open specific port using iptables i.e 3159 Whenever i tried to telnet it generates the following error

Code:

# telnet 172.16.4.100 3195
Trying 172.16.4.100...
telnet: connect to address 172.16.4.100: No route to host
telnet: Unable to connect to remote host: No route to host

but when I stopped iptables

Code:

# service iptables stop

Its working fine

i added the ports in iptables i.e.

Code:

#iptables -A INPUT -p tcp --dport 3195 -j ACCEPT

for safe side I also added telnet port

Code:

# iptables -A INPUT -p tcp --dport 23 -j ACCEPT

but result was same.... In short telnet works without iptables but with iptables it generates the error mentioned above
