AltostratusNAT with PORT LOCKDOWN ??
Hello Experts,
I have a query on locking port and seeking your assistance on this.
I have created a NAT on F5 .
Traffic flow as below: External Client -->F5 (perform NAT from IP1 to IP2) -->Firewall (only allow port 443) --> Server
When External Client is initiating connection on port 22 it is working , however on port 23 getting blocked as expected and I am are trying to find out about this behavior.
Any setting could be done on F5 to prevent port 22 from initiating connection.
Thanks in advance,

If your firewall only allows 443, how is port 22 getting through? If you want to prevent that port from getting TO the firewall, then you could always use a firewall on the F5 (the AFM module) or packet filters.
