Hi there,
yes it is true I am using L2TP without IPSEC (we have wireless links and we are using EAP with WPA2 Enterprise , so we don`t need additional encrypting)
The Changes are made:
we use different Ports for the radius Server, so I added them.
we don`t want to offer any kind of compression so we disabled it completly.
the new mpd.conf for l2tp looks like this
l2tp:
load l2tp0
load l2tp1
load l2tp2
load l2tp3
load l2tp4
load l2tp5
load l2tp6
load l2tp7
load l2tp8
load l2tp9
load l2tp10
........
.....
l2tp1:
new l2tp1 l2tp1
set ipcp ranges 10.65.31.1/32 10.65.254.1/32
load l2tp_standard
l2tp2:
new l2tp2 l2tp2
set ipcp ranges 10.65.31.1/32 10.65.254.2/32
load l2tp_standard
......
l2tp_standard:
set bundle disable multilink
# set bundle enable compression
#set bundle yes crypt-reqd
set ipcp yes vjcomp
# set ipcp ranges 131.188.69.161/32 131.188.69.170/28
#set ccp yes mppc
set iface disable on-demand
#set iface enable proxy-arp
set iface enable tcpmssfix
set iface idle 0
set iface up-script /usr/local/sbin/l2tp-linkup
set iface down-script /usr/local/sbin/vpn-linkdown
set link yes acfcomp protocomp
set link no pap chap
set link enable chap-msv2
set link mtu 1420
set link keep-alive 60 660
set link fsm-timeout 15
set ipcp dns 10.64.1.1 10.64.1.235
set radius server 10.64.1.235 "our secret passwd" 1860 1861
set radius retries 3
set radius timeout 10
set auth enable radius-auth
set radius me 10.64.1.1
set auth enable radius-ac
so I tried to increase the keep alive timeouts and tried to set the link fsm-timeout to 15 (2 is std.)
but nevertheless our connections are dropping from time to time (avergage every 30 minutes)
any ideas about the connection drops?
