I have 2 GLBP routers working fine together for all type of traffic except for PPTP VPN. Nat overload is used on both 1812 routers.
PPTP VPN connection is broken every 3 or 4 minutes if the station uses the GLBP virtual IP as gateway.
If the station uses a 'physical' IP address of one router as the default gateway, the PPTP VPN works fine...
Does anyone has any idea why ?
Here is the GLBP config (I make weight-based load balancing because my 2 dsl lines doesn't have the same line speed) :
ip address 192.168.8.5 255.255.255.0
ip nat inside
glbp 10 ip 192.168.8.4
glbp 10 timers 5 18
glbp 10 priority 150
glbp 10 preempt delay minimum 60
glbp 10 weighting 110 lower 95 upper 105
glbp 10 client-cache maximum 40
glbp 10 load-balancing weighted
glbp 10 authentication md5 key-chain HSRP_KEY
glbp 10 weighting track 100 decrement 20
glbp 10 forwarder preempt delay minimum 60
NAT config :
ip nat translation tcp-timeout 120
ip nat translation udp-timeout 120
ip nat inside source list 120 interface Dialer1 overload
access-list 120 permit ip 192.168.8.0 0.0.0.255 any
Thanks to anybody who could help me.
