Borja, I assume it's the PR submission form that gave you trouble - sorry for that. Based on your report it sounds to me like the bug is in OpenBGPd itself. If it works on OpenBSD with the TCP_MD5SIG option though I'd assume it's due to a difference in our (FreeBSD's) implementation of the option. Did you look at the OpenBSD/FreeBSD differences in your investigation? -Ed Another related query, where adding the TCP_SIGNATURE option reportedly fixed it: http://lists.freebsd.org/pipermail/freebsd-questions/2011-October/234503.html
