This error relates to the device running out of usable ports for a particular object. SNAT is often the culprit but it can also be caused by other objects. If you look at the actual log entry on the device in question it should provide details on the IP address related to the issue and that will help you determine what you need to do.

- What_Lies_Bene1CirrostratusDid you mean to downvote my answer?
- Senthilbabu_S_1NimbostratusHi, Changing the SNAT settings from "Preserve" to "Change" at the VIP configuration will help to fix this issue?
- What_Lies_Bene1CirrostratusNo. Is it a single IP/Automap or a Pool?
- Senthilbabu_S_1NimbostratusWe are using the Automap option in the LTMs.
- Kevin_StewartEmployeeAutomap uses the single self-IP address of the F5 (VLAN appropriate), so that could very well be the issue. Create a SNAT pool with multiple addresses and use that instead.
- Senthilbabu_S_1NimbostratusThis may need a BIG planning with the bussiness units and down time i hope.Changing the SNAT settings from "Preserve" to "Change" at the VIP configuration will help to fix the issue here?
- What_Lies_Bene1CirrostratusNo it won't. Preserve 'attempts' to preserve the original client source IP but if it's in use it will change it (only Preserve Strict won't) so I've no doubt all possible ports are being used. Change will definitely change them all but it won't make a difference.
