Arp Table Size

Is there a list with the capabilities of the ARP table for evry firewall modell? For other vendors it's easy to find.

 

Regards

  • Ok, but wondering about my question wasn't something Special....

     

  • I would like to add:

    maximum number of Firewall Rules or ACL allowed. Checkpoint, Fortigate show this numbers on their datasheet.

    I found this request more frequently on public tenders.

    Thanks

  • HI Robert 

    We do not have a current official document on the product datasheet , But We have added the Firewall Sizing Chart to check which device should you choose for your environment . 

    Since arp entry correlates to an ipaddress would the sizing guide be a 1:1 representation of arp

    The net.ipv4.neigh.default.gc_thres1, 2 ,3  on my system are set to..

     

     

    Thresh1 = the minimum number of entries to keep in arp cache, “garbage collector will not run if there are fewer”

     

    Thresh2 = the soft max to keep, the garbage collector runs after the allowed number exceeds this for5 seconds

     

    Thresh3 = the garbage collector will always run if there are more than this…

     

    So our minimum is 16384 and max is 32768

     

    Which is higher than the values in the tables noted.
