Angry NFS mount fails (times out): NFS server is in DMZ, NFS client is in intranet


Both server (web01), in DMZ, and client (app01), intranet, are Linux OEL5.5.

A few hints follows:

1- I ssh to web01, in DMZ, from a intranet machine on my desktop, export my DISPLAY, and try to bring up xclock; nothing happens.

2- traceroute from web01 to app01 fails.

3- NFS mount from web01, nfs server, to nfs client, app01, fails.

How should my network configuration on web01 or app01 be to make this NFS mount from web01 to app01 work? Each server has 4 NICs, I've only used eth0.

Looks like the firewall is blocking some ports. I do not know the setup, so I could not help .... but you need to look at the firewall ... how many do you have? Do you have single one connected to dmz, internet router and lan or do you have two (one between DMZ and internet router and one between DMZ and LAN)?

Check wikipedia if you do not know what I'm talking about ... correction, if you do not know what I am talking about, contact the local syssie (:= System Admin)!
