There is an issue with the RV180 where it spoofs the first hop on a traceroute to any host outside of your LAN. If you do a traceroute to host1.foo.com the first hop show up as host.foo.com instead of the default gateway (on the WAN side).. This is odd behavior that is just wrong and can screw up monitoring tools.
I have opened Cisco support ticket on it and I expect they will be logging an official bug report shortly. Hopefully there will be a fix in the next firmware release. I'll post any developments to this thread.
