How to PROPERLY achieve MULTI-WAN in pfSense 2.0 ???
Looking for some help on how to PROPERLY achieve a Multi-Wan environment? I've had a look at "outbound load balancing" sticky; but am still a little confused on how to successfully accomplish what I am looking for.
We currently use ClarckConnect for the SOLE purpose of Multi-Wan in combination with a Sonicwall Firewall/VPN Appliance… Recently a colleague of mine recommended I have a look at pfSense 2.0 with its many new developments. I previously played around with pfSense 1.2.2 and while I successfully had FAILOVER working, I never could get reliable multi-wan capabilities; especially the "sticky" connections as I believe they are called? (user would log into an https site, and upon clicking on a link - would be prompted to log in again as the gateway would switch back/forth)...
SCENARIO: We have 3 Internet connections consisting of, T1, Cable, and DSL. Our server has 8 INTEL PRO Gbit NICs. In an effort to maintain speedy internet connections for all of our users, we would like to aggregate all 3 of the above connections - ensuring that all users have adequate bandwidth for their needs.
Using Clarkconnect this is a rather easy process consisting of setting up the nic as "EXTERNAL" and then setting "weights" under the "MULTI-WAN" tab for each connection. Our current setup looks like this:
Should any of the connections FAIL; The connections automatically failover and balance (according to weights) to the remaining 2 active connections.
After looking at the "Outbound Load Balancing Guide" in the sticky section; I assume this is the proper way:
1.) Create A SINGLE(?) Routing Group
2.) Assign Tier1 status to ALL WAN interfaces of Single Routing Group
But how does the LOAD BALANCING work??? Is it simply a round robin? Is there a way to assign "weights" to each interface so that my CABLE interface gets used MORE than say the DSL & T1 interface?
Would I be better to setup MULTIPLE routing groups? i.e.
ROUTING GROUP 1: Cable WAN set as Tier1 (Packet loss/high latency)
ROUTING GROUP 2: DSL WAN set as Tier1 (Packet loss/high latency)
ROUTING GROUP 3: T1 WAN set as Tier 1 (Packet loss/high latency)
? In the above setup, would users get balanced over to Routing group 2 & 3 if for instance, the cable WAN was at capacity???
THANKS FOR ANY INSIGHT..........
P.S. I did read that 2.0 is NOT FOR USE IN PRODUCTION; and am fully aware of this... Our internet access is not MISSION critical - I am simply looking to explore my options vs. our current setup.
certainly on v1.2.2 it's simply a matter of adding multiple instances of the same interface to a load balancing group
We have a 1.5Mbps line with 512Kbps backup, which is always on, so the 1.5Mbps line has three entries in the pool and 512 has one- works fine. Failover is in either direction.
