Need help with ISDN & standard ppp

Post by Praphan Oranphanle » Tue, 07 Jan 2003 13:10:31


I am new to ISDN on FreeBSD and just bought a new Micronet ISDN TA
modem card(Internal) model SP3200AL. My FreeBSD box cannot detect it..
(FreeBSD 4.4-RELEASE). Can anyone tell me how to detect it.

Then.. after that can I run PPP on analog modem (external) and PPP on
ISDN modem (above one) both and nat http packet through analogmodem
but non-standard port through ISDN?? If possible, how can I do that?
Please lead me..

Best Regards/Praphan O.


1. ppp && PPPoE && ADSL && net && buffer(s)

i have a freebsd box (4.8-RELEASE) and a italian ADSL (256/128 if i remember good) line.
sometimes my freebsd box (that i use as firewall in my little lan) became stalled.
no data arrive and with ping IP i get error about some buffers full.
in ppp.log i see a lot of:
Jun 24 22:45:39 firewall ppp[66]: tun0: Phase: Clearing choked output queue

i search with google on newsgroups but i don't find nothing that work :)

i put some info on the configuration, because i read a lot of question about this parameters :)

kernel config:
maxusers        64
options         NMBCLUSTERS=32768       #expand nic buffer

in ppp.conf:
add default HISADDR

netstat -m:
1/400/131072 mbufs in use (current/peak/max):
        1 mbufs allocated to data
0/182/32768 mbuf clusters in use (current/peak/max)
464 Kbytes allocated to network (0% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines

netstat -t:
