Did you see any sctp address among the listening sockets printed on startup? Any log message?
yes, both proxies reported at startup that they are listening on sctp.
It is possible that you don't have a kernel with sctp support (in which case the sctp support will be automatically disabled on startup). Try enable_sctp = 1 in .cfg to get instead and error.
no error messages if i include enable_sctp=1 in config. i can make more experiments later. i sort of gave up and my test setup is not now ready.
