[ANSS-netops] Verizon - Important information about transition to IPv6

[Doug Neuhauser]

Chris,

At the BSL we are currently using IPSEC VPN tunnels between a cell modem
router at our seismic sites and a central site router.

If our acquistion system also wants to remain in IPV4 address space,
can the IPSEC VPN tunnels between the 2 public IPV6 addresses of the routers
be defined to tunnel IPV4?  IE can you define an tunnel for IPV4
traffic using IPV6 endpoints?  Or is this done by doing NAT on both ends?

Let me know if my question is not clear.
Thanks.
- Doug N
