Hi

I've tried to understand this one for some months.  There was a 
previous message about this but can't find it in the archive.  Been 
asked to send ISDN questions to the i386 list and so here it is.

My ISDN confiuration is correct as far as I can work out.  Looked at 
all the documentation.  Asked a few people.  Should be correct.  But, 
I find that whilst I am connected to the net - configured to work as 
doal on demand - the NetBSD firewall box will suddenly disconnect 
after about 2 or 3 minutes whilst packets are being routed from my 
internal network to the outside world and back again.  Can't find 
anyone who knows what this is about.  So, thought I might try asking 
here again. Anyone know how to fix this so that I can connect and get 
hold of the updates for my internal machines ?  Just now I can't stay 
online for long enough to do this.

 My /etc/isdnd.rc file can be seen below.....  I've tried to change 
the idletime values but that has no effect.  .....
