CARP messing with route and VIP
boujid last edited by
i had 2 servers where PfSense (2.3.2) is installed with 2 NIC for each server, each NIC with 2 VLANs so 4 DMZ used per server, i had problems with CARP so i had added 2 other physical NICs, now my 4 DMZ each one use a physical NIC for each server
my DMZs are
LAN (192.168.1.1 and 192.168.1.2)
3 VIP for CARP
CARP_WAN1 associated with WAN1
CARP_WAN2 associated with WAN2
CARP_LAN associated with LAN (192.168.1.3/32)
i have 3 gateways configured
GWWAN1 for WAN1
GWWAN2 for WAN2
GWLAN for LAN
the GWWAN1 and GWWAN2 are configured directly in the interfaces WAN1 and WAN2
GWLAN is configured in "static routes" where i added 10 routes to some servers
CARP is well configured, in the master all (XMLRPC Sync) are selected
the problem :
when i do some changes in the Master and i do apply, i am getting on the backup server
"Interface specified for the virtual IP address 192.168.1.3 does not exist. Skipping this VIP"
checking the backup server, i notice that the CARP_LAN is no more associated with LAN but with WAN1 !!!
checking the gateways, i notice that the gateway GWLAN changed to disabled and this gateway is no more associated with LAN but with WAN1 !!!
i have done the test many many times, same problem
i deleted the LAN gateway, the LAN CARP VIP and re-add them without success
each time, the same problem, the interface assicated to the LAN gateway and to the LAN CARP VIP changes automatically on the backup server when i do some changes in the alias of the master for example
if i uncheck "Static Route configuration", "Virtual IPs" in (XMLRPC Sync) on the Master, the CARP works perfectly
if i uncheck just "Static Route configuration" in (XMLRPC Sync) on the Master, the LAN gateway stay ok and active on the backup but the LAN CARP VIP is faulty as its interface change from LAN to WAN1 automatically
please any hint to resolve the problem ?

Use the same interface order on both boxes. For instance, if WAN1 is assigned to network port re0 and WAN2 to re1 on master, ensure that the interfaces are assigned the same way on the backup box.

they are aleady absolutely the same for both servers (Master and Backup)
bge0 –- WAN1
bge1 --- WAN2
em0 ---- LAN
em1 ---- HA
