Indeed - about three months ago the IP address of www.par.univie.ac.at 
has changed from .100 to .80 in the 131.130.186. network.

I can't speak for sunsolve.sun.com, but the address for 
www.par.univie.ac.at shouldn't change again soon. You could add 
131.130.186.0/25 instead, which should be even longer lasting.

Best thing would be to use a stateful firewall setting, of course, as 
all connections will originate from pca inside your network.

Martin.
