I'm having one server with public IP x.x.x.32/29 I need to add this in my firewall asa 5520. so that from outside my network no one can access it.

I want to know how can i do this,shall I add this server directly in my network or create static nat to it and pass through firewall.

As I am new in firewalls

Kind Regards

Hello,

So you do not want anyone on the outside world to access that server.

Just put it on your network and make sure you deny all traffic from any user to x.x.x.32.

Regards,

Julio

Hello Majed,

static (inside,outside) tcp x.x.x32 51241 x.x.x32 51241

access-list Outside_access_in permit tcp specific_outside_hosts host x.x.x.32 eq 51241

Let me know if this is what you are looking for?

Thanks,

but the correct syntax was:

access-list Outside_access_in extended permit tcp any host x.x.x.33 eq 51241

static (inside,Outside) x.x.x.33 172.x.x.25 netmask 255.255.255.255
