More Info: - Neither rebooting the FW nor the linux machine did change anything
- changing the load balancing from "arp balancing" to "ip balancing" did not change anything.
- At first I thought it might be a problem of the switch and it has an "old" virtual IP address cached. However, the log on the FW does show that the machgine itself replies to to the arp-request, does it not?
- it happened "suddenly". I did change a pf-rule and restarted pf; however I did not restart networking (AFAIK)
- unfortunately I cannot determine whether the "wrong" lladdress was used as virtual address before. I did not note it down, before this happened.
