Primary internet connection is on ste0 and performs NAT with pf to re0, re1 and ste1. 12 through the default gw 10. 1 ? On my Linux boxes I would set up 2 routing tables, one for each default gateway, then I can say: ip rule add from 10. 128. Additional context #9185 also impact FreeBSD (version 12), but state that this only affect route without gateway (ie: only pointing to an interface) Checklist Slightly embarrassing, but I was totally ignorant of setfib(1) and the possibility of per-process routing tables. This FIB solution on FreeBSD is just incredible! Thank you very much . It normally is not needed, as a system routing table management daemon, such as routed(8), should tend to this task.

An IP-address at that place would be the next-hop where to send the packet. I am rather assuming that NAT is being done in the modem here. 1. Both nfe0 and wlan0 get DHCP addresses from two separate Internet Service Providers (ISP). The routing metric is used by the routing protocol (routed). So, how do I configure routing (set gateway) for a jail from the host? To display your default FIB (routing table, FIB 0), simply use netstat. This post will attempt to list out a few ways to display route table and also how to assign default route aka default gateway in Linux & FreeBSD. 4 The FreeBSD L2 address translation table has been reimplemented to reduce lock contention on parallel processing and simplify the routing logic. All working very good. When the local system needs to make a connection to a remote host, it I'm porting an application from Linux to FreeBSD that needs to look at the table of network routes ("route" on Linux or "netstat -r" on FreeBSD).
