When I want to build "Freetz-NG" with vtun, build fails with lfd_encrypt.c:102:23: error: storage size of 'ctx_dec_ecb' isn't known:

Disabling FREETZ_PACKAGE_VTUN makes build of "Freetz-NG" continuing.

vrun should be updated for openssl 3, report it there

Done, upstream report ↗ here.

In the meantime it might be advisable to disable vtun build if no
matching OpenSSL version is available in Freetz-NG.

Regards!

or simply sleect an compatible openssl version

or simply sleect an compatible openssl version

I have only OpenSSL version 3 to select in "Freetz-NG"'s make menuconfig.

Anyway, I do not need vtun. I just reported to let you know that the build system here is able to select package combinations that won't compile, so you could add a dependency logic that prohibits this (I have seen another package that has such a dependency logic on version of a library).

This is possible. Im sure i could find more problems, but the biggest problem is that there is noone who fixes them. But you could be the first
