Load balancer inside firewall or not...
-
I am using HAProxy only as a proxy right now in a couple places (for Exchange on prem). But the load balancing setup is super simple.
I like it.
-
HAProxy is really powerful. We use quite a few of them here.
-
You would put the HAProxy behind the firewall, right?

Generally, yes. Because you don't want to load balance things that you want to block.

Right. For example, my firewall only sends ports 443 and 80 to haproxy.

Are you looking to load balance two ISP connections or two servers inside your network providing access to the outside?

The OP clearly stated that the firewalls were already going to be setup for failover.
This is clearly a load balancer for the backend services. Not the WAN link..

I also wonder about SSL for load balancers. Is it best to use SSL passthrough or SSL termination?
It has to terminate, or else it cannot load balance.

Aww I didn't know what this meant, exactly
after the firewalls (pfsense in fail-over config).
But in seeing your response - OK yeah, the firewalls will be in fail-over config...
-
Wasn't pfsense in production, I guess I would say, "frowned upon"?

Yes, one firewall will do the work and the other one will be in standby. All firewall states are synced between them. If the first one fails the other one will take over all the IPs and duties.
Load balancer will send the request that passes the firewall to different webservers. If one webserver dies the other one(s) will do the job.

Will you also have HA for the load balancers?

Maybe, I don't care. Pfsense is just a customized freebsd installation with a gui as far as I'm concerned. And freebsd is solid.

Yes, but I'm not sure how I will set it up. If firewall-1 goes down (completely or NIC failure) then firewall-2 will take over and that also means loadbalancer-2 will take over.

Yes it is.
If you wanted to run a VM as your firewall, is there something that would be recommended?

Oh yeah. I remember that now. Thanks.

Yes it is.
I disagree, pfSense is an absolutely solid choice.
VyOS is even better, but there is nothing wrong with pfSense.
It is how some people use it that causes problems.

Do you have some points on how people's use causes problems? TIA
