Subject: Need Network Engineer for Small Project
Need Network Engineer to consult/guide for a few hours on a small project.

Existing: Three node mesh VPN between three locations.  Been in-place
since 2012.  Recently upgraded VPN devices (Linksys LRT-224's) as a part
of the next step.  However, the VPN device at one node is not the
default gateway for that LAN segment - the old device is as it is bound
to a public IP address that the customer's customers access by IP
address and not name.  Added static routes to LAN devices to route
traffic to the other two nodes via the VPN device.  This has been
working since September. This doesn't mean we can't reconfigure if we
have to.

Next Step: Customer wants two ISP connections using different media. 
Old ISP is Cox Business.  New ISP is CenturyLink.  Have installed new
devices at office and data center and created second VPN tunnel between
these two nodes.  Unable to get traffic to reliably use second VPN.  I
can get the traffic to go down the CenturyLink VPN, but only by
configuring the CenturyLink devices with the same IP addresses as the
Cox devices.  This is OK for an emergency, but not the desired end result.

Final step: Get traffic to fail-over from one tunnel to the other when
the primary VPN fails.  Cox has already notified customer that the cable
needs to be replaced and there will be several days of downtime, so this
is a certainty.

Lots more details to share.  Need to show topology.  If you're with me
at this point, saying "Uh-huh, George, easy stuff" then please email
me.  I'm willing to pay, so this will get you some fine craft beer, not
that free beer.  I anticipate a preliminary meeting to discuss
requirements, then some on-site working sessions.
