It is just the security paranoia, yes.

   /I don't know of any way to do it within SGE, but it should be easy
   enough with a host-based firewall (e.g. iptables on Linux). /

This answers it perfectly, thanks. Firewall is the answer.
Best,

What are you trying to achieve?? Doesn't the Linux firewall handle the

The execd only handles requests from the qmaster, and also in the
tight PE integration case from the machine running the Rank 0 of the
parallel job.

It is a security related thing, or there is a real use case for
restricting the subnet??
