Hi Bongjae,
I tested your proposal, and it worked fine. During the test,
I monitored port status by using netstat command. The result was as follows.
[root_at_rx200-4 ~]# netstat -a -u
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
udp 0 0 *:666 *:*
udp 0 0 *:669 *:*
udp 0 0 *:sunrpc *:*
udp 0 0 *:ipp *:*
udp 304 0 rx200-4:5060 *:*
udp 0 0 *:5061 *:*
udp 0 0 *:5062 *:*
udp 0 0 rx200-4:54368 rx200-4:5061 ESTABLISHED
udp 0 0 rx200-4:54369 rx200-4:5062 ESTABLISHED
I want to use the send port as 5060, not 54369 or 54368.
Is it possible to do that in grizzly?
