Title: Dual Wan failover problem (DFL-800)
Post by: Walle on August 03, 2010, 10:07:33 AM
Hi

I just want failover if one wan connection goes down.

I have two wan connections
Wan1 DHCP 100 mbit
Wan2 Static 2 mbit

One main route as follow
                        
1  Route  wan2  wan2net           95    No    Access over backup ADSL
2  Route  wan2  all-nets  wan2_gw                   95    No    Access over backup ADSL
3  Route  wan1  wan1net           90    Yes    Primary access over fiber
4  Route  wan1  all-nets  wan1_gw                   90    Yes    Primary access over fiber

Interface group with wan1 and wan2

Failover is working if I remove the Wan1 cable then it switch to Wan2 but not if I leave it in.

Route monitoring with ping to some large websites in Sweden (Do I need a ICMP rule for this to work from the firewall?).

Firmware version 2.26.01

Best regards Johan

I have disabled monitoring on wan1 and it still dosen't work.

Monitoring disabled
Remove cable from wan1 = no internet access
Remove DHCP option on wan1 (Gets no ip) = no internet access

Monitor enable
Remove cable from wan1 = internet access over wan2
Remove DHCP option on wan1 (Gets no ip) = no internet access

Hey Johan what did you do? I have the same problem in my dfl-800.

"Monitor for Route Failover
   The health of a route may be monitored for route failover purposes.
    Monitor"
Is this dan is talking about?

In softwares later than 2.25, better to use only ICMP monitoring for routes.
