Hello team,
I am currently writing because I have a problem, recently I have received many alerts about IPSec Tunnel, in the sophos XG interface the tunnel does not show as "down", but I receive many alerts and the following message in the log viewer.
the received CHILD_SA proposals did not match: ESP:AES_CBC_256/HMAC_SHA2_256_128/MODP_1536/NO_EXT_SEQ, ESP:AES_CBC_256/AES_CBC_192/AES_CBC_128/HMAC_SHA2_512_256/HMAC_SHA2_384_192/HMAC_SHA2_256_128/AES_XCBC_96/NO_EXT_SEQ (Remote: 200.188.17.132)
Users do not actually report failures, but alerts continue to show
