connection refused

hi guys,
i am getting a connection refused exception while trying to use rmi object created in a server machine from a client machine.
i am getting a "no route to host is the exception".
is this related with firewall settings
i tried my best in the web to find a solution and made several changes. but nothing is working for me.
i dont know what to do for the network settings, can you guys help me.

'No route to host' would suggest your attempted connection is being blocked, I would check your firewall settings.

hi guys,
thank you.
this is my iptables setting.
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere tcp dpt:ssh flags:SYN,RST,ACK/SYN
ACCEPT tcp -- anywhere anywhere tcp flags:SYN,RST,ACK/SYN
ACCEPT tcp -- anywhere anywhere tcp flags:SYN,RST,ACK/SYN
ACCEPT tcp -- anywhere anywhere tcp dpts:1024:65535 flags:SYN,RST,ACK/SYN
ACCEPT tcp -- anywhere anywhere tcp dpt:rmi flags:SYN,RST,ACK/SYN

Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT ipv6-crypt-- anywhere anywhere
ACCEPT ipv6-auth-- anywhere anywhere
ACCEPT udp -- anywhere 224.0.0.251 udp dpt:5353
ACCEPT udp -- anywhere anywhere udp dpt:ipp
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:rmi
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:9000
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

is this the real problem.

thanks in advance

hi guys,
since no comments about the iptables configuration, i think this is the best ( and may be the maximum) configuration that i can provide in my situation.
is it a problem that i have not restarted the iptables after making additional changes to the existing ones.
but once i restarted the iptables on the remote machine, i failed ssh access on the remote system.
any helps regarding this

thanks in advance
