Problem accessing ports even without firewall on CentOS


Hi All,
I'm running a CentOS server on a Vmware demo machine and have problems accessing certain ports on the machine.

"nmap localhost" run locally reports all ports correctly available and access to the ports is working properly. However, "nmap <ip of my machine>" run from another client DOES NOT report the same ports available (see output below).

I'm NOT running iptables or ipchains. I'm on an internal network with no firewall/router intervention.

nmap localhost output:
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
111/tcp open rpcbind
631/tcp open ipp
926/tcp open unknown
1489/tcp open dmdocbroker
1497/tcp open rfx-lm
1521/tcp open oracle
32771/tcp open sometimes-rpc5

nmap from remote client:
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
631/tcp open ipp
926/tcp open unknown
1521/tcp open oracle
32771/tcp open sometimes-rpc5

I need to access the ports 1489 and 1497 remotely (smtp is not configured so probably only accepts access from localhost).

Any ideas?
