Hi !
I have some issues when i use more than one pptp vpn connection.
My configuration :
OpenWRT BARRIER BREAKER (14.07, r42625)
TP-Link TL-WDR4300 v1
/etc/config/network (UMTS/HSDPA Internet CONNECTION):
config interface 'wan'
option proto '3g'
option service 'umts_only'
option apn 'APN'
option delegate '0'
option device '/dev/ttyUSB0'
cat /etc/ppp/options.pptp
noipdefault
noauth
nobsdcomp
nodeflate
idle 0
mppe required,no40,no56,stateless
maxfail 0
cat vpn_loop
#!/bin/sh
while(true)
do
while ( test $(ifconfig 3g-wan 2>&1 | grep inet | wc -l) -eq 0 ) do
sleep 3; done
sleep 10
pppd nodetach debug call PEERNAME
done
cat /etc/ppp/peers/PEERNAME
plugin "/usr/lib/pppd/2.4.7/pptp.so"
pptp_server (SERVERADDRESS)
pptp_window 100
mppe required,no40,no56,stateless
name username
remotename connectionname
file /etc/ppp/options.pptp
ipparam vpnconnection
cat ip-up
#!/bin/sh
case "$6" in
wan)
route del default
route del default
route add default dev $1
vpnconnection)
route del -net 192.168.0.0/16
route add -net 192.168.0.0/16 dev $1
route del -net 10.0.0.0/8
route add -net 10.0.0.0/8 dev $1
;;
esac
All required Packages are from the standard BARRIER BREAKER release.
As long as i only have the Internet Connection + 1 VPN everything looks
fine.
As soon as i add another VPN Connection (to another server) the VPNs are
performing
very poor. When the Internet Connection is weak, it looks like no traffic
goes through the VPN anymore.
I think the Problem was there in RC3 too, but not so extreme.
(RC3 hat an older pptp Kernel Module)
Unlukily i could not find anything in the logfiles, that could
help to find problem.
Is there a way to increase the verbosity level for the pppd or the pptp
module to get
more information into the logfiles ?
