hi all ,
im here to ask about some feature of cisco QOS NBAR ,
as we now http traffic is on port 80
now some users use some proxies
as an example
77.88.66.77 with port 66000 and can bypass the lan proxy
my quesgtion is :
can NBAR detect people who use custome proxies with different 80 port and estimate that the are using proxies and deny them ??
regards
