Hi to all,

I am interested in the implementation of IPsec module. When I run Kamailio, it is creating processes based on the below formulate:

UDP children * IPSEC_MAX_CONN * interfaces (v4 and v6) + (TCP+UD) processes for each interface.

For example:

children = 16

tcp_children=16

IPSEC_MAX_CONN = 25

and two interface : IPv6 and V4

Kamailio process count = (16 * 25 * 2 ) + 16 + 16 = 832

But why IPsec module is listening to UDP not TCP? this is an internal connection?

Thank you.

Regards,

Hossein
