3048.0. "Problems with DECbridge 90 filtering" by PCSUP1::ventriglia () Fri Dec 08 1995 12:52

Hi,

I am having a few problems with a DECbridge 90. I want to set it up, so only LAT (60-04) is 
forwarded. I put the bridge in "invert mode", as the manual suggests: enabling a filter to forward 
the desired protocol should block all other protocols, except those defined to be forwarded.

After I did that, I could see with a protocol analyzer, that everything was being forwarded 
(DECnet, NetBeui, TCP/IP, etc...). Is that a BUG or did I miss something in my configuration?

Another question is: How can I set up a filter to block NetBeui?

Thanks in advance for any help. Regards,

Roberto
