RPC Problem while mounting NFS File System

Question

Hi,
We have two servers. ca1 and bench
Currently we moved bench across the firewall in DMZ. Now ca1 and bench are on opposite sides of the firewall. We have made sure that port 111, 2049 and 4045 along with the default telnet and ftp ports are programmed in firewall to provide access.
We can telnet and ftp from bench to ca1.
When we try to NFS mount a ca1 filesystem at bench using following command :
bench:>mount ca1:/u07/export /ca1/u07/export
we get following error :
nfs mount: ca1: : RPC: Timed out
This is happening since we moved the bench server across the firewall.
What could be the problem?
Cheers,
MS

Hi,
Thanks for the help.
It seems like that the nfs service is already started on the server.
Here are the results :
# ps -ef | grep nfsd
root 366 1 0 Jul 12 ? 0:00 /usr/lib/nfs/nfsd -a 16
root 25791 25789 0 16:16:45 pts/5 0:00 grep nfsd
# ps -ef | grep mountd
root 218 1 0 Jul 12 ? 0:05 /usr/lib/autofs/automountd
root 364 1 0 Jul 12 ? 0:00 /usr/lib/nfs/mountd
root 25793 25789 0 16:16:53 pts/5 0:00 grep mountd
# ps -ef | grep statd
root 201 1 0 Jul 12 ? 0:00 /usr/lib/nfs/statd
root 25797 25789 0 16:16:59 pts/5 0:00 grep statd
# ps -ef | grep lockd
root 203 1 0 Jul 12 ? 0:00 /usr/lib/nfs/lockd
root 25799 25789 0 16:17:07 pts/5 0:00 grep lockd
Please let me know what else can be done. This problem started after we moved these machines on different sides of the firewall.
