    Hi guys, is there a way to see the NAT/PAT table, probably the answer is show datapath session table but is there a good way to just show how many internal users are PAT to my external IP address, lets say users comming from a 172.24.0.0/24 network and going to 1.1.1.1 adress (1.1.1.1 in this example is my public routable address)

    From AirHeads:

    How do I check whether the NAT translations are active?

    Product and Software: This article applies to all Aruba controllers and ArubaOS versions.

    For the global NAT table:

    (Aruba) #show datapath nat table

    Datapath NAT Table Entries

    --------------------------

    Pool SIP Start SIP End DIP

    ---- --------------- --------------- ---------------

    0 10.13.106.255 10.13.106.255 10.13.106.255

    For the specific AP:

    (Aruba3200) #show datapath nat ap-name Sam-AP125

    Datapath NAT Table Entries

    --------------------------

    Pool SIP Start SIP End DIP

    ---- --------------- --------------- ---------------

    0 172.16.0.253 172.16.0.253 172.16.0.253

    Hi, ok, but how can i check how many ports am i using out of the 65535 ephemeral ports. I am having a weird issue were traffic seems to stop working for a couple of seconds/minutes and it might be i am port address translating all my addresses to 1 "external" address. Just want to be able to confirm it.
