Comcast Modem and CARP
-
I want to setup failover with 2 pfsense boxes. The particular modems we have do not even see Gratuitous ARP packets. Will this be a problem if I am trying to use CARP to setup two redundant pfsense boxes?
A little background: I am not using these as firewalls. I am using these purely to load balance WAN traffic (I have setup GW groups and firewall rules for this). I am also doing inbound and outbound NATing.
Currently in production we are using a single vyatta box and I have already configured a pfsense box to have identical settings(pfsense does load balancing a little differently but I made it the same). The problem with the vyatta box is that when one fails and the other becomes master, the IP address is fine and it uses VRRP but the MAC address does not failover to the other box. The problem with this is that the comcast modem is looking for the previous MAC address of the interface that went down. In the end it will eventually timeout and fail over but until that happens it means lots of downtime. I need it to failover as quickly as possible.
Is there a way to "failover" the MAC address in pfsense?
Sorry if this has been asked before but I have seen many posts about comcast modems but none with answers that are similar to what I am asking. I also was unlucky when looking for mac address failover.
Any help would be appreciated.
