IP Compression
Select whether compression is to be activated before data en-
cryption. If data is compressed effectively, this can result in
higher performance and a lower volume of data to be trans-
ferred. In the case of fast lines or data that cannot be com-
pressed, you are advised against using this option as the per-
formance can be significantly affected by the increased effort
during compression.

20 seconds, the SA is discarded as invalid.
