Could there be a router between you and the remote machine which blocks port 98? If I port-scan my own machine (on a university network) from a host outside the university, then several port are listed as "filtered" -- some of which I know are open, and some I know are closed. These are all caused by port blocks on the university's external routers. Might something similar be the case here? HTH, Zak.
