CARP with OpenVPN
I have setup two pfsense box and both are synching together using carp just fine and I was able to connect to the internet when the LAN computer using the CARP VIP as gateway.
Now I have openVPN setup for both pfsense box with same configuration, right now our remote client connect to the VPN using the public IP address of the firewall1 (Primary), now the problem is if the primary firewall is down and the secondary firewall take over, I am for sure that our remote VPN client will not be able to connect because it was looking for the IP address of firewall1.
I know that you can setup a CARP cluster public IP address thourgh Advance Outbound NAT but I don't know how to do this as I already have setup 1:1 NAT for our mail server. If I've setup a Advance Outbound NAT for CARP cluster public IP address is this mean that my 1:1 nat will be ignored and not going to work anymore that all outbound connection will now be the CARP cluster public IP address?
Any help would be much appreciated.
