G'day list,
I have 3.2-RELEASE and using Greg Lehey's The Complete FreeBSD 3rd
Edition plus resources on www.freebsd.org (and links) and this list it was a
doddle to configure this box with ipfw, nat, dns, sendmail, pppd, etc etc etc.
At the moment I use pppd to connect to our ISP (I can't remember why I
picked pppd over ppp).
Anyhow, I now want to use ppp and multi-link ppp to aggregate the 2
modems to our ISP on the assumption that it will give us greater bandwith.
I'll start with my ppp.conf below, I won't post the 400+ lines of log output
unless required.
When I start ppp thus, "ppp -ddial mp":
1. both logins seem to be made,
2. tun0 is brought up, netstat -rn appears as for a single-link ppp, the log
shows
tun0: IPCP: myaddr aaa.bbb.ccc.146 hisaddr = aaa.bbb.ccc.1
3. query to the diagnostic port "show mp" reveals that multi-link ppp isn't
enabled,
4. ping from the tun0 interface works OK,
5. there is no socket created in /var/run.
To prove single-link ppp is OK, I have 2 other ppp.conf sections, mp0 and
mp1, which connect just fine on tun0 and tun1, and I can ping out of either
interface.
As an aside, I find it a bit odd that my ISP returns the _same_ remote
address for each link. We are given 2 addresses aaa.bbb.ccc.146 and
aaa.bbb.ccc.147, by default he always returns aaa.bbb.ccc.1, so I force the
147 remote address to be aaa.bbb.ccc.2 and get no complaint.
Is there a command I'm missing from ppp.conf (below), and what do I look for
in the log to tell me why multi-link ppp failed to be established.
TIA, taras
