Thanks and apologies for the lack of info/clarity.
There is only one ISA firewall and this is what I want:
LAN –> ISA --> pfSense (3 WAN) --> internet
I basically would like the ISA firewall to handle firewall/filtering, and the pfsense to act as an open router to the firewall. So if I decided to connect a client directly to pfsense such as:
client --> pfsense; I would expect unfiltered access to the net without any protection but still have loadbalancing. Is this any clearer?
The WANs are terminated as IPs from adsl modem/routers.
Thanks again.
