Current set up is Static to Static,
due to ISP changes we are loosing the static on the 1700. If I setup dynamic DNS behind the 1700 could I use a FQDN in the crypo isakmp policy?
i.e.) crypto isakmp key <thekey> address <the FQDN>
and then in the map do
crypto map <name> <#> ipsec-isakmp
set peer <the FQDN>
set transform-set <transform>
the 1700 is an ISDN connection
alternative is going T1 at X2 the cost and buying a WIC, and a plane ticket....
Yes you can, you can use different sequence numbers for the two crypto maps. Place the static one first and then the dynamic one.
