      Hello,

      I use pfsense 1.2b1 in a datacenter for colocation, i have 62 public IP's from xxx.xxx.xxx.128 to 191, the colocation gateway is xxx.xxx.xxx.129, subnet mask 255.255.255.192

      I have 4 nic's, my pfsense ip is xxx.xxx.xxx.130

      WAN (xxx.xxx.xxx.130/26, Gateway : xxx.xxx.xxx.129)
      |
      LAN (192.168.2.1/24)
      |
      OPT1 (bridged with WAN)
      |
      OPT2 (LAN2, 192.168.1.1/24)

      I want use 8 public IP's from my 64 IPs to do NAT on LAN2
      So I create 8 VIPs (xxx.xxx.xxx.176-184) and create NAT 1:1 to my LAN2

      The problem is the 8 Ip's i used with VIPs(CARPS) are in the subnet xxx.xxx.xxx.130/26 bridged with WAN.
      So when a packet arrive, it's send to the OPT1 interface & OPT2, i create a simple rule on the firewall for ICMP from WAN to my VIPs adresse, and one rule on my OPT2 to WAN, no problem everyting work fine.
      But i always have in my firewall log and deny message for this packet :
      if : OPT1 | destination xxx.xxx.xxx.176

      How to resolve this routing problem ?
