[SR-Users] asking odd mediaproxy,,

[Rakhmadhany Primananda]

I've just setting SIP Express Router and Mediaproxy in 1 PC. Then, I'm
setting in NAT Router that only activated for MASQUERADE like this:
iptables -A POSTROUTING -s 172.17.2.0/24 -o eth1 -j MASQUERADE

NB:I assume in network 10.100.0.0/24 (eth1) as public IP and
172.17.2.0/24as private IP.

When I calling with x-lite and activated mediaproxy service, the connection
running well with 2 direction (full duplex from 10.x.x.x to 172.x.x.x
conversely).But,when I stopping mediaproxy service (for proving that voice
packet if pass NAT will connect half duplex or maybe broken),apparently this
connection still running well with 2 direction

my question,,
why this happened?
are having trouble with mediaproxy or SIP Express Router?
i'm confusing,,

thanks very much,,
:)
