(ASCEND) How to reserve modem ports for MAXDial?
We recently installed a MAX 2024 (now running 5.0Ai28). I've been trying for
a month to get an answer from Ascend support to a dialin routing question
(originally I was working to get a useful answer, but I've heard nothing for
about two weeks, so now just about any answer would do). Can someone here
explain what's going on?
Our MAX has a subnetted class B address (say, 138.152.108.3/24) and one pool
of IP addresses for dialin users (21 addresses starting at 138.152.111.65).
RIP and OSPF are both turned off; a couple of static routes is all we need.
Our PPP dial-in user profile is typically:
user Password = "pass"
Service-Type = Framed,
Framed-Protocol = PPP,
Framed-IP-Netmask = 255.255.255.224,
Framed-Routing = None,
Ascend-Assign-IP-Pool = 1,
Ascend-Idle-Limit = 300
The problem is the Framed-IP-Netmask. Including it means our profiles work,
but we get an extraneous (albeit harmless, so far) network route added when
a client dials in, e.g., for a client dialing in and getting IP
138.152.111.73, then in addition to the required host route:
Destination Gateway IF Flg Pref Met
138.152.111.73/32 138.152.111.73 wan67 rT 100 1
we also get a network route for the entire dial-in pool subnet:
138.152.111.0/27 138.152.111.65 wan67 rGT 100 1
However, if we remove the Framed-IP-Netmask from the profile, then dialin
clients have no connectivity. With 5.0Ap42, the problem was that the MAX
created an incorrect route for the client which pointed, not to the wan
port, but to the MAX's ethernet interface, e.g.,
Destination Gateway IF
138.152.111.73/32 138.152.108.3 ie0
Not very useful... 5.0Ai28 is different, but no better. With it, removing
the Framed-IP-Netmask causes the MAX to create no route at all for a dialin
client:

224.0.0.9/32 - local CP 0 0 0
255.255.255.255/32 - ie0 CP 0 0 185
i.e., no route at all to 138.152.111.72!
Can anyone suggest explanations for this?
