Use pfsense as an internal load balancer
-
Hello, I was hoping someone could help with this, or even offer another solution.
We have 25 PFsense firewalls in our network, each with a different net block. We are an Internet search engine. I have the LAN side of each firewall in 4 VLANs.
What I would like to do is simplify the load balancing of the firewalls for our developers; this would have many benefits as well.
I would like to have the developers send their requests to one IP, for each VLAN, then have that device round robin between the firewalls.
This way as I add more firewalls the developers don't need to know I just add them to the list. Plus our developers can open 20 instances on one server; right now all 20 go out the default gateway. If I was load balancing each request would go out a different gateway, this would simplify and improve things dramatically.
I was hoping to use Pfsense then make a cluster for HA.
Is this possible?
Thanks

How many paths to the internet there and at what speed?

We are in a large data center. Each firewall has it's own external network, we try to get them as different as possible. So each one is a different path. One VLAN has over 600 servers. manually load balancing the gateways is painful. Plus when I add a new firewall its a pain to go change 20-30 machines to use it. If the whole VLAN used one IP as it's gateway, and that device could round robin each connection to a different firewall, that woudl simplify everything tremendously. I would just add the new firewall to the list, instead of 20-30 servers. Plus, we have some machines that spin up 20 different processes, I would love for each process to have a different gateway, instead of all having to use one.
We have a full gigabit to the Internet, everything in our data center is gigabit.
Thanks, I am open to any suggestions if there's a better way to do it.
