  • 1.  Add 2nd ISP to be used by only one network.

    Posted 21 days ago

    Using an SRX1500 on 21.2 

    Currently all of our networks are are using a single ISP for all internet traffic. We are exploring adding a 2nd ISP that will be used exclusively by one of our internal networks. Anything on 10.40.0.0/24 should use ISP2. 

    ISP2 would be all NAT'd traffic, no need for a DMZ zone.  The ability to use ISP2 as a backup for ISP1 would be nice but not necessary a requirement for this.  

    Currently we are just routing everything 0.0.0.0 to our single default gateway.  How do I setup the SRX to route 10.40.0.0/24 via ISP2?

    You can use filter based forwarding to direct all the traffic sourced from that subnet to the desired ISP.  This scenario is covered in the following kb article.
