PFSENSE Load Balancer on the same VLAN
I set up a VIP via the pfsense load balancer.
All client accesses that are not in the same vlan as the load balancer pool servers are OK.
But for clients present on the same vlan as the pool, it's KO.
From what I understood the load balancer relay the IP of one of the servers in the pool to the client. Hence my problem.
I put my VIPs on a new DMZ and I set up a nat outbound on this DMZ to nat the source IP of all the requests to my VIPs but without success.
Is what I am trying to do possible?
You can solve that with some carefully crafted NAT rules, but you are better off removing that config and using the HAProxy package instead. Since it's a real proxy, it would not have that issue.
The built-in load balancer has been removed from 2.5.0, so it's a dead end to start with it now.
thank you for your reply.
I have tested several NAT possibilities but none match in case the client is on the same vlan as the server pool (even if the VIP is in a specific DMZ).
I am in 2-5-1 and the load balencer service is still present for the time being.
For the moment, I have not succeeded in getting HAProxy to work despite the various help we can get on the various forums. It must be said that most of the aids are for Web load balancing. I am trying to do LDAP and DNS type TCP ... and this to automate my failovers on my two sites (nominal and its backup).
I will resume my tests on HA Proxy.
2.5 has not been released yet. 2.5.1 does not exist so I imagine you must be running 2.4.5p1?
For relayd see:
But, yeah, you should switch to HAProxy now to be ready for 2.5.
Indeed I was wrong in the version. It's good 2.4.5p1.
Following the advice to use the HAProxy, I tried again and managed to set up my VIPs last night.
So I am ready for the next versions of pfsense.
Thanks again to everyone.
