- Deterministic NAT translations are not using all the translation addresses and ports configured. - Run command dnatutil --action summary will display N times the number of subscribers
Only a fraction of the translation addresses and ports available will be used. If you have 2 virtual servers - 1/2 the translation space. 3 virtual servers - 1/3rd the space. This could result in more frequent translation failures if a there are not enough ports available to each subscriber.
- LSN pool using deterministic mode - 2 or more virtual servers using this same LSN pool and the same source address range
None
