I solved the problem by configuring a second IP to the interface statically
in /etc/network/interfaces:
# The primary network interface
auto eth0
iface eth0 inet dhcp
# Server IP
auto eth0:1
iface eth0:1 inet static
address 192.168.11.10
netmask 255.255.255.0
There are a couple advantages to this.... my favorite is that I can portmap to
the static address in my router and only bind those services to the static IP
while services I use internally (such as samba) are hosted on the dynamic IP.
I hope this helped!
