Carp not working correctly on internal firewalls
I have 2 external Pfsense firewalls all working well and using CARP, however when i set up two more pfsense boxs inside the network when i add one CARP address, the system still works but when i add two CARP address's, it causes the network to slow and not work correctly.
The set up is as follows:
WAN IP xx.xx.xx.xx WAN IP xx.xx.xx.xx
LAN IP 10.10.1.21 LAN IP 10.10.1.22
Web Server1 / Web Server2
WAN IP 10.10.1.29 WAN IP 10.10.1.30
LAN IP 10.11.1.1 LAN IP 10.11.1.2
So as soon as i set up both CARP devices on the second set of firewalls this is when the problems start. I can nowever set up the one CARP address eg. 10.10.1.28 and this seems to work fine, its only when the second is added i get issues.
Figured out where i was going wrong on this - on the first set of firewalls i was using VHID 1 /2 and the same for the second internal firewalls, silly mistake - after setting the internal to VHID 3 /4 it is all working correctly. ;D
