Hi guys, first of all sorry for my english, I will try to explain my problem.
I have 2 ESXI ( Version 6.0 ) Servers. This Servers has 4 NIC's, 2 for WAN and 2 for LAN. I configured on both ESXI Servers Promiscue Mode, Mac Address Changes, Forged Transmits, Route based on IP Hash, Net.ReversePathFwdCheckPromisc = 1 and Net.ReversePathFwdCheck = 0.
I have many VIPS configured on my Primary Node with differents VLANs, advbase 1 advskew 100 on VIPS.
I try to change advkew to 0 on Mater Node, but without success.
The problem occurs when I want to sync VIP's on Master Node to the Backup Node, after configure High Avail Sync and click in Save (Backup Node) the Interfaces on both servers flopping their status. Backup Node change to Master, after 2 seconds this node change to Backup again and I lost connection on both servers.
I read many articles but I didn't find any solutions, anyone could help me with this problem?
Try to disable Virtual IP sync in XMLRPC (I had some issue with it in the past)
Align Advertising Frequency for VIP's in on both nodes, and manually set skew to 1 on Master and 100 on Backup.
If still not stable, the pfSense doc's recommend to increase Adv.Freq. with 1 until stable situation has achieved….
