In one custom dynamic application, the inside client connects to an outside server using TCP port 4444 and negotiates return client traffic in the port range of 5000 to 5500. The server then starts streaming UDP data to the client on the negotiated port in the specified range. Which Cisco ASA feature or command supports this custom dynamic application?
A.
TCPnormalizer
B.
TCP intercept
C.
ip verify command
D.
established command
E.
tcp-map and tcp-options commands
F.
set connection advanced-options command
E.
tcp-map and tcp-options commands
I would say rather D is correct
for example:
established tcp 4444 0 permitfrom tcp 5000-5500
I have the same idea. D
