Client has 2 backbone connections. Adding a PIX to one WAN link; PIX will terminate a VPN from a remote 831.
Client wants to add a load balancing appliance to add fault tolerance to outbound traffic (understands if PIX's WAN is down, VPN will be down).
Initial approach would be to make a small non-public (ie 172.16.0.0) subnet between the LAN ports of PIX and router on other WAN to the WAN ports of the load balancer. Load balancer would be gateway of office LAN (10.0.0.0). Remote office (homed by the 831) would be on 10.0.1.0)
DOes anybody see a problem with routing VPN traffic between the 10.0.0.0 and 10.0.1.0 LANs?
Thank you all in advance.
