You are telling the machine that the 192.168.1 net exists on both xl0 and xl1. It exists on only one or the other of them. To which interface do you expect it to send a packet destined for 192.168.1.7? > #route delete -net 192.168.1.0 > #route add -net default 192.168.1.1 > #route add -net 192.168.1.0 -interface 192.168.1.3 > #netstat -r This is still pretty bogus. The 192.168.1.0 route is before the other one, or it doesn't know how to frind the gateway 192.168.1.1, since it doesn't know which interface to write to. > This shows no problems at all and works whether I use the routing daemon > or use static routes at boot up, however -current will not allow me to > do the same thing that I have done above, instead I get the following: [ ... ] > bash-2.05a# ifconfig xl1 192.168.1.3 netmask 255.255.255.0 > ifconfig: ioctl (SIOCAIFADDR): File exists > > The only thing which I can think of is that either a) it is a userland > change in -current, or b) I was only ever running the GENERIC kernel for > 4.5-RELEASE and never recompiled my kernel until I was compiling with > -current source so maybe it is some option in the GENERIC config file > for the -current source.

Change the netmask to 255.255.255.255 to tell it that it is a point-to-point link. If you want to build a bridge, then you need to turn on ip forwarding (net.inet.ip.forwarding=1). Really, you need to think through your network setup a bit more; each interface needs to be on its own network, so if you mask off the top parts using the netmask, no two interfaces are equal. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
