[c-nsp] ASA 5520 to Pix sudden loss of tunnel

[Christopher J. Wargaski]

Scott--

   One way traffic like this is usually caused by one of three things:
1) The interesting traffic ACLs not being mirror images of each other.
2) An outbound ACL is denying traffic across the IPsec tunnel
3) Routing is not sending the traffic for the remote subnet to the PIX/ASA
