NFSv3 config files for static ports

[sirquijote@lavabit.com]

Hi,

Debian 6.0.7.

I'm trying to set up NFSv3 with static ports for use with a firewall.  The
only walkthrough I've found on this is for Red Hat, which says:
"To allow clients to access NFS shares behind a firewall, edit the
/etc/sysconfig/nfs configuration file to control which ports the required
RPC services run on."
I don't have a /etc/sysconfig directory on Debian.  Should I just create
it or is this config file put somewhere else on Debian?

Thanks.

PS: NFSv4 is buggy on the client platform so can't be used.
