I'm trying to find a way to set a default outbound IP address for system-generated traffic like syslog or FTP of configurations. This would be most helpful for SRX appliances that have multiple routes, VPNs, etc.
For instance, if I try to ping a host across a VPN I'm trying to send data to, I get no response. If I use the -source with a LAN-side IP of the SRX, I am able to ping the host. I've configured that host to in the syslog system settings of the SRX, but no syslog traffic is reaching that host.
