Error after Upgrading to 6.1.10

[stjones]

I upgraded our Panorama and two PA3020's in a HA setup this morning. Afterwords I am getting the following errors committing from Panorama to our PA3020's.

• Details:
• . Configuration committed successfully
• Warnings:
• . vsys1 (vsys1)
• . Warning: NAT DIPP rule Source-NAT-Rules: Needed translated addresses space after multplying oversubscrition ratio(2) is 508, which exceeds the per rule limitation of 256.
• . We auto-degrade the oversubscription ratio to 1 for this rule.
• . (Module: device)

Any help to resolve would be appriciated.

Hi @stjones !

Could you add a screenshot of your nat rule? it appears the ip range used in 'source-nat-rules' is too large

The 'per rule' maximum allocated DIPP addresses for your platform is 256 which has an oversubscription multiplier of 2 which makes available additional ports per source address (this is a new feature in PAN-OS 6.1, see articles below). If you need to have more source addresses, the oversubscription multiplier could cause the nat pool to gow too large as the number would surpass the device limitations

you can either decrease the IP pool allowcated to the rule, or you can disable the multiplier, opening up more space for source IP addresses

> configure 
Entering configuration mode
