Linux config for remote login oracle enterprise manager

Question

Hi, all
I setup oracle 10gr2 on my redhat linux server. I can login oracle enterprise manager locally, using firefox browser. But I can't connect to it using other computer. How should I check and configure the linux please?
Thanks first!

Thank you guys for all your replies! It works after I stop the iptables service. But if I want to keep the firewall, how should I configure iptables please? Could you give me an example? My iptables look like this:
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
