In intercept mode, the TCP intercept software intercepts TCP synchronization 
(SYN) packets from clients to servers that match an extended access list. The 
software establishes a connection with the client on behalf of the destination 
server, and if successful, establishes the connection with the server on behalf 
of the client and knits the two half-connections together transparently. Thus, 
connection attempts from unreachable hosts will never reach the server. The 
software continues to intercept and forward packets throughout the duration of 
the connection. The number of SYNs per second and the number of concurrent 
connections proxied depends on the platform, memory, processor, and other 
factors

In watch mode, the IOS passively watches the connection requests flowing 
through the router. If a connection fails to get established in a configurable 
interval, the software intervenes and terminates the connection attempt.

Thank you,
