Hi


Your permimeter router will load balance between the 2 firewalls. Whether it does it per packet or per destination depends on how you setup the router.


You need to be careful with this as you may well get asymetric routing - goes out one firewall and comes in the other. If your firewall are active/active this may not be a problem but it could be if you are running in active/standby.
