If the firewall software is properly setup, it shouldn't hurt, and probably can 
help.

Interesting.  From  other messages, you are running a newer version the of the 
TCP stack software than I am, so maybe this is remenats of that or of the 
dial-up connectivity.  I don't see these three entries on my Warp 4, Fix Pak 9 
based system.  I've applied what I think are the latest fixes for the 4.0 
stack.  Any way....  Since these are port "0",  the three entries should be 
just local table entries, possibly needed or setup by InJoy.


 SB> What fixes?

Depends on the TCP and MPTS level you are running.  You are running a newer 
stack than I am, so I haven't even attempted to keep track of any fixes for the 
4.3 TCP stack.  There is a web page that folks reference for Warp updates that 
has a fairly good layout of the options for TCP and MPTS updates.  There are 
numerous options.  So far, I've stayed with the free TCP 4.0 updates to the 
Warp 4 system that I have.

Take care.....
