Hi

I think it support up to 255 IPsec tunnels with security license. 

IPsec traffic is restricted on the

Cisco ISR 4451-X. The router has the sa

me IPsec functionality as a Cisco ISR

G2. The default behavior of the router will be as follows (unless an HSECK9 license is installed):

•

If the limit of 225 concurrent IPsec tunnels is exceeded, no more tunnels are allowed and the

following error message appears:

%CERM-4-TUNNEL_LIMIT: Maximum tunnel limit of 225 reached for Crypto functionality

with securityk9 technology package license
