Two external IPs

megamaced · 05-01-2008, 09:53 PM

Hello HWF!

I was wondering if it is possible to configure two external interfaces, from different ISPs, and use NAT for the internal network? See my tacky diagram for a better understanding of what I am trying to achieve!

If such a configuration is possible, once a client on the internal network has been mapped in NAT for ISP1 for example, is it possible they could switch to using ISP2 randomly?

Cheers

yes this is possible, and it goes one step further... you can use both connections at the same time! (more or less, it just keeps track of what physical connection is being used to talk to different hosts, and balances it over all the connections)

pfSense supports multiple WAN interfaces with load balancing right out of the box: pfSense » Features
