MultiWan don't Balance @ 100 %



  • Hello everybody,

    Firstly i would thank all people of this forum by making PFSense such a great tool (and plz excuse my poor english  ::)  )

    I'm trying to user a MultiWan configuration on our office, and my choose was about PFSense, i've read a many guide about this but no one helped me tu resolve my issue.

    This is what i have now :

    _______________WAN1
    Lan |
          |_______________WAN2

    i have a "GatewayBalancing" wich contain the both gateways of the differant WANs (Tier1 and Tier2)

    A firewall rule wich allow any traffic going out by using the GatewayBalancing group.

    My problem is like this

    I start a "ping -t" to an external address and then turn down the WAN1 interface (by ssh) then the ping stop. @ this time PFsense must route the traffic through the WAN2 and the ping must continu but it's not happened ! But if a open a new prompt window and start a new ping -t it works !!  :-\

    Add to this the failover balancing take between 10 to 20 sec to take effect  :-\

    Thanks for help ! ^_^

  • Txs for replaying.

    Ok i've change that, but even that the traffic still don't redirect to the other wan connection.  :-\

    Can you describe how do you test the load balance ?

    I tested load balance since the 2.0 Beta (Dec 2010) till current 2.0.1 and for me it works.

    You must set the Gateway-Group in your firewall rules as the gateway!
    Try this:
    http://pfsense.org/ip.php
    Refresh the page many times fast after another and if IP changes then LoadBalance is working.



  • Hi,

    Txs guys for helping.
    This topic was very useful too balancing/failover issue

    However i have a question about ping. When i test with a web page the loadbalancing/failover work perfectly and when i use a ping it stop and the ping don't restart but if a start a new ping it works.  :-\

    Any idea ?

    Take a look at SYSTEM -> ADVANCED
    There is something about resetting firewall states after one Gateway goes down.



  • There is the checked option in the System -> Advanced menu:

    SYSTEM -> ADVANCED -> Firewall/NAT
    Disable NAT Reflection for port forwards
    Disable NAT Reflection for 1:1 NAT

    SYSTEM -> ADVANCED -> Networking
    Hardware TCP Segmentation Offloading
    Hardware Large Receive Offloading

    System: Advanced: Miscellaneous
    Load Balancing ->  Use sticky connections
    Security Associations -> Prefer older IPsec SAs
    Schedule -> States
    Gateway Monitoring  -> States
