I have a remote server that i would like to scan. The remote subnet is
192.168.100.0/24. However when I connect to the remote subnet via the cisco VPN
I am provided a dhcp address of 192.168.3.3/24. These are obviously different
subnets but the cisco VPN handles the two subnets seamlessly such that a
tracert from 192.168.3.3 to 192.168.100.226 yields only one hop.Note that there
is no gateway provided by the VPN DHCP.

The connectivity is there and I have full access to the subnet (no acls).
However it appears that nessus does not like the fact it cannot find the
logical default gateway of my subnet. see the log file below. How can I scan
this subnet through the VPN? See the first line.
