Default Re: Can you use "custom NAT" with ISP redundancy?
No, sorry I think I wasn't clear,

Lets say I have ISP A and ISP B each with a defined subnet,

Firewall has two external IPs:
ISP A: 1.2.3.4
ISP B: 5.6.7.8

We are currently using an IP different from the gateway's IP for NATing, i.e.
all external traffic goes out as 1.2.3.5 instead of 1.2.3.4

How do I configure it so that it does the same thing for ISP B if its doable....

Hope its clearer this time
