thank you so much for the explanation, Here is my config
so the access-list 101 permit tcp any host 200.38.120.133 eq www ssh will block all and only allow www ssh to that IP? right?
Can you check if the config look ok ? So all I do is just assign one of the /27 IP to a server say .133 and use the gateway .2 right? thank again for all the help. I really appreciate this
