How to Setup Multi WAN+CARP+FTP on DMZ+SQUID

[Tony]

Hi,

I am having problem setting up FTP on carp, my FTP server is connected to the pfsense interface bridge to WAN and I called it DMZ. I have two pfsense setup as CARP and once I connected the backup pfsense to the DMZ switch the LAN network lost connection to the internet. Another thing I am also trying to setup Multi WAN to both pfsense how do I do that?

Please see attached network setup, hoping for your recommendation on how to setup properly this kind of network setup.

Any help would be greatly appreciated.

Thanks.
