Fred,
It is quite possible I've misunderstood the problem :-) but have
you tried anything like
import socket
tc_local_port = 9999
tc_remote_port = 9999
outgoing_if = "172.16.1.2" # say
remote_tc_host = "172.16.1.3" # say
# udp is the default for DGRAM
tc_sock = socket(socket.AF_INET, socket.SOCK_DGRAM)
tc_sock.bind((outgoing_if, tc_local_port))
tc_sock.connect((remote_tc_host, tc_remote_port))
If you send data with tc_sock, it should have a source port of
tc_local_port.
So, to set the source port, call bind. You should do that before
calling connect, since
calling connect on an unbound socket has the side effect of
assigning an ephemeral port to the socket.
Hope that was of some help to you.
All the best,
Keir.
