Afaik, I don't need to have IP forwarding turned on on my laptop or other device connected to that subnet in order to ping the carrier's router which is located on that very same subnet.

The firewall is an OpenBSD 5.0 amd64 firewall which uses the carrier router as default gateway and which has my own routable /24 network behind it. Now I have already configured my firewall for CARP but didn't add a second CARP firewall yet on that subnet. Now if on that very same subnet I plug another device/laptop, I am unable to ping the carrier's router. For me this is totally weird, as I am able to ping my firewall and the firewall can also ping the carrier's router. So I was wondering if this might have something to do with my firewall using CARP on that subnet? Looking at the arp table on that other device or laptop I have plugged in on that same subnet I see the following entry for the carrier's router (IP address masked out): ? (xxx.xxx.xxx.xxx) at (incomplete) on em0 So it looks like it is unable to get the hardware/MAC address of the carrier's router... but why? I can't explain it myself. Anyone has an idea? Regards, ML
