Thank you very much for that help - unfortunately Igot the wrong information
and stated the problem slightly incorrect.
In reality, the rc.conf in question is:
defaultrouter=10.10.10.1
ifconfig_fxp0=inet 10.10.10.2 netmask 255.255.255.0
ifconfig_fxp0_alias0=inet 20.20.20.2 netmask 255.255.255.0
so, the router in question that has address 10.10.10.1 also has address
20.20.20.1 - however, either one will work as the default gateway for BOTH
subnets, which is why the rc.conf above works (using one default gateway for
both addresses on fxp0) however, I still get:
/kernel: arplookup 10.10.10.1 failed: host is not on local network
because 20.20.20.2 arplookups 10.10.10.1 and it isn't local. BUT it still
works - all packets from the 20.20.20.2 alias work just fine using
10.10.10.1 as a gateway.
So how do I alter things (that are actually working ok) to get rid of those
error messages ? I think I could do it two ways - one, add a second gateway
for the 20.20.20.0/24 subnet for those aliases, OR ... well actually I guess
that is the only way to do it.
So what is the rc.conf syntax to do that ?
Hi,
I have a system with IPs assigned from 192.168.0.0/24 and 192.168.1.0/24
Right now I have this in my rc.conf:
defaultrouter=10.10.10.10
ifconfig_fxp0=inet 192.168.0.1 netmask 255.255.255.0
ifconfig_fxp0_alias0=inet 192.168.0.2 netmask 255.255.255.255
ifconfig_fxp0_alias1=inet 192.168.1.1 netmask 255.255.255.255
So, as you can see I have one default route, and both /24s use that
single
10.10.10.10 as the default router. But, because I have simply added the
192.168.1.1 IP as one more plain old alias, I now get this in my logs:
/kernel: arplookup 10.10.10.10 failed: host is not on local network
So, how do I add 192.168.1.1 as an alias, without adding another
defaultrouter, since my current defaultrouter setting is already correct
?
The problem is not with the aliases - it is (as the message says) because
the default router is not on a local network. If the router is attached
via fxp0, then try adding an alias like this:
ifconfig_fxp0_alias2=inet 10.10.10.1 netmask 255.255.255.0
Then your system will know which interface to use to talk to 10.10.10.10.
