3943RE: [BPQ32] Issues with BPQEther port ?
- Sep 29, 2010
MessageMisco,Yes 08FF is the default Ethertype for BPQEther, though it can be changed.Firewalls don't usually look at anything other than IP, so I'm a bit surprised that the firewall is causing problems. Maybe it is confused by the 08FF frames. Perhaps you could try a different firewall.73,John-----Original Message-----

I found today that my firewall (Sygate Personal Firewall) is the
obstacle that causes the problem of 'freezing' the ethernet link between
BPQ 4.08a (or 4.09d) on a DOS machine, and BPQ32 on a Windows machine.
When the firewall is on (well, always), the ethernet link goes down or
better to say 'freezes' after a while. I mean, when I activate both ends
of the ethernet link, the nodes keep exchanging their node-lists,
beacons etc without problems. When I add some traffic (Eg. forwarding
between two bbs's running on top of BPQ), everything goes fine but only
for some few minutes, but soon after the BPQ32 side seems to lose its
capability to 'hear' the other side of the link and 'freezes' itself
(sometimes it freezes the whole computer). However, sometimes I still
get beacons and node-lists from the DOS machine (i see them coming in
the BPQ32 monitoring window), but BPQ32 seems to be incapable to
'digest' incoming information and include it to its own node-list, etc.
When I switch off the firewall and wait half a minute, the frozen link
'melts' and continues to work. Any suggestion what to do to avoid that
This is my test station:

I just tested the packets by using Ethereal and noticed that all packets
between two nodes were of protocol type '08FF' (is that a 'BPQ protocol'?)
