I have the setup depicted in the following figure:
A pfSense box with a LAN interface and two interfaces facing internet with real IP addresses conected to an external router.
Each internet subnets (A.0.0.0 and B.0.0.0 in the example) is a /29 where in both cases the external router has the .1 address and pfSense has addresses from .2 to .6
I want to NAT some outgoing traffic from LAN using addresses in A network and some using the B network... NOTE: I dont want to load-balance internet access I just want traffic NATed out with the real IP address of my choice...
Questions:
What would be the default gateway of the pfsense box? Both A.0.0.1 and B.0.0.1?
If the above were the case. Would pfSense smartly select the correct gateway depending on what address I use for NAT? That is, if I srcNAT with address, say A.0.0.3 it will handle that traffic...
