cipe tunnel doesn't start automatically

Hi,

I have a CIPE Tunnel between to Dial-In Linux Server with static
ip adresses.

The problem: If the tunnel ist down and someone tries to connect
to the remote net, the cipe tunnel doesn't start automatically, You
first have to ping the ptp addr:

Server A: 192.168.10.1
Gateway A:  1.100.15.1
|
| (internet)
|
Gateway B: 1.100.15.2
Server B: 192.168.11.1

So if the tunnel is down and someone tries to ping server A from
server B the tunnel doesnt start, it only start when i ping Gateway A
from Server B - or Gateway B from Server A.

Here is my configuration:

// --- CIPE-Configuration of  Gateway A -----------
//
# IP address of the CIPE device
ipaddr           1.100.15.1
# IP address of the peer device (i.e. the CIPE device on the other end).
ptpaddr          1.100.15.2
# IP adress of the local device
me               145.253.203.113:8105
# IP adress of the remote device
peer             217.110.152.210:8105
# The link key.
key              [.....]
# Dynamic key lifetime in seconds
tokey            60
# Key exchange timestamp timeout
tokxts           30

// --- CIPE-Configuration of Gateway B --------
//
# IP address of the CIPE device
ipaddr           1.100.15.2
# IP address of the peer device (i.e. the CIPE de
ptpaddr          1.100.15.1
# IP adress of the local device
me               217.110.152.210:8105
# IP adress of the remote device
peer             145.253.203.113:8105
# The link key.
key              [...]
# Dynamic key lifetime in seconds
tokey            60
# Key exchange timestamp timeout
tokxts           30
maxerr 1000

// --- ip-up of Gateway A
/sbin/route add -net 192.168.11.0  netmask 255.255.255.0 gw 1.100.15.2

// --- ip-up of Gateway B
/sbin/route add -net 192.168.10.0  netmask 255.255.255.0 gw 1.100.15.1

Both, Server A and Server B have a default router over their Gateways..

Has someone an idea what could be wrong? If the cipe tunnel ist up,
everything
works perfectly!
