Need help with Iptable/Firewall on RHEL.

Hi Gurus,

I am facing an issue with firewalls on one of my Linux Box.

Issue : Port 8001 looks open to me and there is a weblogic process running on it

Code:

netstat -alnp | grep 8001
tcp        0      0 ::ffff:3.20.247.165:8001    :::*                        LISTEN      28768/java

Code:

lsof -ni tcp:8001
COMMAND   PID   USER   FD   TYPE    DEVICE SIZE NODE NAME
java    28768 xxxxxxx  362u  IPv6 348588617       TCP 3.20.247.165:vcom-tunnel (LISTEN)

but when I try to connect to that port externally I am not able to I tested using telnet to check that but failed. it said could not connect. Can you suggest how to check if this port is blocked outside the OS .

Thanks In Advance.
Rama Krishna.
