MultiWan don't Balance @ 100 %

pfsuser

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 ! ^_^

If you want "Load balance" then Both GW must be in same TIER

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.

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

pfsuser

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
