> Some tricky attackers could try to use Asterisk TLS port as HTTP/HTTPS proxy. Of course, that won't work for them, but the log is polluted with the following warnings and errors:
> {code}
> [May 10 14:21:21] ERROR[19119]: tcptls.c:609 handle_tcptls_connection: Problem setting up ssl connection: error:00000000:lib(0):func(0):reason(0)
> [May 10 14:21:21] WARNING[19119]: tcptls.c:684 handle_tcptls_connection: FILE * open failed!
> [May 10 14:21:21] ERROR[19141]: tcptls.c:609 handle_tcptls_connection: Problem setting up ssl connection: error:1407609B:SSL routines:SSL23_GET_CLIENT_HELLO:https proxy request
> [May 10 14:21:21] WARNING[19141]: tcptls.c:684 handle_tcptls_connection: FILE * open failed!
> {code}
> It would be nice to see offending IP here to feed the log to something like fail2ban to have attackers banned.
