Subject: [asterisk-users] Curious problem with NAT
Hi list!
Since the internal calls work as expected and I can register my Asterisk on an
external provider, I'd like to add a new feature and allow my mobile phone
to connect to my Asterisk and manage calls.
Well, first of all, my Asterisk is NOT direct on Internet available, but behind
a NAT.
So I configured my sip.conf:
localnet=192.168.200.0/24
externhost=myhost.noip.com
externrefresh=180
Then I added the peer in my users.con:
[00491771111111]
fullname = 00491771111111
secret = MYVERYSECRET
type=peer
nat=yes
qualify=yes
qualifyfreq=60
hassip = yes
dahdichan = 1
transport=udp,tcp
callwaiting = no
context = default
host = dynamic
dtmfmode=rfc2833
dial=SIP/00491771111111
and finally "core reload".
On my Gateway I configured the NAT so:
/sbin/iptables -t nat -A PREROUTING -p udp --sport 6060 -j DNAT --to-destination
192.168.200.120:5060 /sbin/iptables -t nat -A PREROUTING -p tcp --sport 6060 -j
DNAT --to-destination 192.168.200.120:5060 /sbin/iptables -t nat -A PREROUTING
-p udp --dport 6060 -j DNAT --to-destination 192.168.200.120:5060 /sbin/iptables
-t nat -A PREROUTING -p tcp --dport 6060 -j DNAT --to-destination
192.168.200.120:5060
Well, the phone connect to the server and I can see it reachable:
OpenWrt*CLI> sip show peers
Name/username Host Dyn Forcerport
ACL Port Status
00491771111111/0049177111 192.168.200.3 D N
40702 OK (1768 ms)
Well, now I call the mobile phone from another peer. It rings and I can answer
the call.
Wonderful!
But no word will be sent... :(
I cannot hear anything on my mobile phone and I cannot transmit a single
word....
I tried to connect my mobile phone to a public VoIP-Provider and it works as
expected, so I'm sure that the problem is on my network, but I can't
find it...
What am I doing wrong?
Thanks a lot
