I'll try. This is from reality, however IPs and phone #s are forged ;)

3511234      Password = "Ascend-CLID"
        User-Service = Framed-User,
        User-Name = "bifi-gate",
        Ascend-Metric = 7,
        Framed-Protocol = PPP,
        Framed-Address = 192.168.1.254,
        Framed-Netmask = 255.255.255.0,
        Framed-Routing = None,
        Framed-Compression = Van-Jacobsen-TCP-IP,
        Ascend-Link-Compression = Link-Comp-Stac,
        Ascend-Idle-Limit = 80,
        Ascend-Data-Svc = Switched-64K

bifi-gate-out    Password = "ascend" User-Service = Dialout-Framed-User
        User-Name = "bifi-gate",
        Ascend-Metric = 7,
        Framed-Protocol = PPP,
        Framed-Address = 192.168.1.255,
        Framed-Netmask = 255.255.255.0,
        Framed-Routing = None,
        Framed-Compression = Van-Jacobsen-TCP-IP,
        Ascend-Link-Compression = Link-Comp-Stac,
        Ascend-Idle-Limit = 10,
        Ascend-Data-Svc = Switched-64K,
        Ascend-Dial-Number = "03511234",
        Ascend-Expect-Callback = Expect-Callback-Yes

As you can see, the outgoing profile fakes the remote IP to be the broad-
cast of the remote LAN, simply because the router there will never have
this IP. It also specifies a very short idle limit (dunno whether that
makes any difference because packets are due to be transmitted anyway)
and it specifies Expect-Callback-Yes in order to prevent it from dialing
over and over again _if_ the response really comes and the callback itself
is delayed a bit.

Works as expected, for a number of customers.

Andre.
