[site A] pc A -> firewall A-> internet (VPN) -> [site B] firewall B -> linux1, linux2
linux1: 1.1.1.1 (ip alias 1.1.1.3)
linux2: 1.1.1.2
1.1.1.3 will be switched between linux1 and linux2.
pc A accesses linux1, linux2 via VPN.
when 1.1.1.3 is switched to linux2. pc A could access it.
within site B, 1.1.1.3 could be accessed by linux2 and other PC.
I checked the arp table in firewall B. the MAC of 1.1.1.3 is either missing or wrong (pointed to linux1). that is the reason why pc A could not access 1.1.1.3
the ipalias is added by gnome->system->admin->network
Pls advise how to let firewall B to know the correct MAC addr when the ip alias is changed to another PC.
