NFS Mount

Hi there,
I have a problem mounting a NFS share frm a remote computer. We have
the following scenario:
Computer A (RedHat Linux): Two Directorys, which are shared via NFS
(one IP)
Computer B (RedHat Linux): Client (Two IPs; one for ssh, the other for
NFS)
The computers are connected via Internet trough VPN

When I try to mount the NFS share from Computer B, i get an error
message ( "mount: RPC: Timed out"). I mounted the shares local with
success. Even mounting the shares from another computer in the network
runs without problems. It seems that both computers are configured
correct.
All required services are installed, except NFSLock.

Any idea???

portmap running on both machines?

Yes, portmap ist running. A few more words to the configuration....
Computer B is behind a firewall. It has the physical IP 192.xxx.xxx.xx.
This IP is restricted for ssh from the outside. NFS is only accessible
via 195.xxx.xxx.xxx. This IP is noticed in the DMZ-Configuration of the
Firewall.
rpcinfo -u 192.xxx.xxx.xx from Computer A fails
rpcinfo -u 195.xxx.xxx.xx from Computer A succeeds

I think mount is using the physical connection, as described above, RPC
fails on this IP.

What does "showmount" produce, and what is in the appropriate /etc/exports
file?
