Did you need to patch anything for openswan? Can you share your patches

I am not sure what you mean when you bundle "sha-md5" and "des and aes".
A tunnel needs both an encryption algorithm (aes or 3des) and an
authentication algothim (sha1, sha2, md5, etc). So for your tunnel
to work, you would always be using either md5 or sha? Since you say
some tunnels work, those algorithms must be working?
I am not sure I understand exacly what works and what does not work.
