CARP IPs Broken

[symon92]

Our setup:

2 WANS and 1 LAN
Each WAN has 16 IPs that connect to the LAN.

WAN A uses an IP address to connect to ISP
WAN B uses bridged mode to connect to ISP

Now what we did:

We added each of the 16 IPs as virtual IPs using CARP and each one being a master, Initially when we added the IPs with firewall rules we pinged and each one worked.
Although we had tried pARP before but they werent pingable.

PROBLEM: none of the IPs are pingable (we did not change firewall rules since they were pingable first.)

Any idea what the problem could be here?

Any help would be appreciated.
