The remote lab is accessed via a PIX firewall, RL-PIX-CSVPN, reachable from
the Internet. The trainer will initiate an IPsec VPN tunnel terminating on RL-PIXCSVPN.
RL-PIX-CSVPN forwards all traffic to a Cisco 2621 router, RL-RMTCSVPN,
which routes traffic based on the source IP address to one of two routers,
RL-RMT1-CSVPN or RL-RMT2-CSVPN. These routers will perform IP address
NATing and route the traffic to the necessary student pod.
