Hi Marco, > Here is the charon.log: I hope it will be useful for you.
Thanks for the update. This is a bug introduced with the changes that attempt to keep the proposal selection for IKEv1 more consistent (returning the lifetimes of the actually selected transform and the correct proposal and transform IDs). Determining the correct lifetimes now depends on the selected proposal/transform. Unfortunately, there was one location in the code (as Quick Mode responder) where the proposal might not be defined when the lifetimes are determined. This caused the crash here as no matching proposal was selected: > [CFG] <apsil-10.221.128.183|25> selecting proposal: > [CFG] <apsil-10.221.128.183|25> no acceptable DIFFIE_HELLMAN_GROUP found > [CFG] <apsil-10.221.128.183|25> selecting proposal: > [CFG] <apsil-10.221.128.183|25> no acceptable ENCRYPTION_ALGORITHM found > [CFG] <apsil-10.221.128.183|25> received proposals: > ESP:3DES_CBC/HMAC_SHA1_96/NO_EXT_SEQ > [CFG] <apsil-10.221.128.183|25> configured proposals: > ESP:3DES_CBC/HMAC_SHA1_96/MODP_1024/NO_EXT_SEQ, > ESP:AES_CBC_128/AES_CBC_192/AES_CBC_256/HMAC_SHA2_256_128/HMAC_SHA2_384_192/HMAC_SHA2_512_256/HMAC_SHA1_96/AES_XCBC_96/NO_EXT_SEQ I pushed a fix to master [1]. I guess we'll be releasing 5.8.4 soon. Regards, Tobias [1] https://git.strongswan.org/?p=strongswan.git;a=commitdiff;h=cb26c554
