Hi everybody,

I've configured SER to work with mediaproxy, I also configured mediaproxy.ini. My clients are authenticating normally, but only the clients that has a Public IP (ex. 200.201.145.146), all the cliets that are behind NAT can't REGISTER. What may be wrong ? Do anyone uses SER 0.9.0 with mysql authentication and Mediaproxy that could give me a hand ? My ser.cfg and mediaproxy.ini are as follows

================== ser.cfg ====================== debug=3 fork=yes log_stderror=no

listen=192.0.2.13 # put your server IP address here port=5060 children=4

dns=no rev_dns=no

This should match the value for ; mediaproxy_socket in ser.cfg ; Default value: /var/run/proxydispatcher.sock ; ; group Put the socket in this group and make it group writable. ; Default value: ser ; ; defaultProxy Default mediaproxy to use in case the From/To domains ; involved in the call don't define any. ; Valid values for this are: ; ; - None ; don't use any default proxies. domains without ; mediaproxy SRV records won't work ; - /path/to/unix/socket ; use a single MediaProxy server identified by the given ; UNIX socket path ; - IP_or_hostname[:port] ; use a single MediaProxy server identified by its network ; address. The network address consists of an IP address ; or a hostname and an optional port number separated by ; a double colon. If port is missing 25060 will be assumed. ; Examples: ; 10.0.0.1 (connect to 10.0.0.1 on port 25060) ; 10.0.0.1:90 (connect to 10.0.0.1 on port 90) ; mp1.mydomain.com ; mp1.mydomain.com:7000 ; - domain://domain_name ; Use all MediaProxies defined by domain_name, honoring ; their priority and weight to create a cluster of proxies ; with fallback and load balancing capabilities. ; ; Default value: /var/run/mediaproxy.sock ; start = yes socket = /var/run/proxydispatcher.sock group = ser defaultProxy = /var/run/mediaproxy.sock

[MediaProxy] ; ; Section for configuring the MediaProxy server ; ; The following options are available here: ; ; start Boolean value that specifies if to start the RTP proxy server. ; Default value: Yes ; ; socket Path to the UNIX socket where MediaProxy receives ; commands from the dispatcher or SER. ; Default value: /var/run/mediaproxy.sock ; ; group Put the socket in this group and make it group writable. ; Default value: ser ; ; listen Network address where MediaProxy receives commands from ; a remote dispatcher. ; Valid values for this are: ; ; - None ; don't listen for network connections at all ; - address[:port] ; listen on the specified address and port ; address can be an IP a hostname or the keyword Any ; (in which case it will listen on 0.0.0.0). If address is ; a hostname, that should map in DNS to an IP address ; present on the machine through an A record. ; If port is missing assume 25060. ; ; Default value: None ; ; allow List of addresses that are allowed to connect to this ; MediaProxy server and send commands. ; They are specified as a comma separated list of entries, with ; each entry being specified in the CIDR network/mask notation ; (ex. 10.0.0.0/8) ; ; In addition simple IP addresses or hostnames are allowed, in ; which case the mask is considered to be 32. ; ; In addition to network ranges/addresses 2 keywords can be used ; for this option: ; None to specify that none is allowed to connect (not very ; useful but this is the default for security reasons) ; Any to specify that anyone is allowed to connect ; (dangerous!) ; ; Example: allow = 10.0.0.0/24, home-pc.mydomain.com, 1.2.3.4 ; ; Default value: None ; ; proxyIP IP address to use to talk to the phones.

However first found usually means ; first defined in /etc/hosts which may not be what you want. ; If you find that the address that's automatically selected is ; not the one you want, you can specify the right one using this ; option. The address must be one that's present on one of the ; host's interfaces. ; ; portRange The range of ports to use for proxying the rtp streams. ; This option is specified as minport:maxport with minport and ; maxport being even numbers in the range 1024-65536 ; Default value: 35000:65000 ; ; TOS Unless you know what TOS means, leave this option alone. ; The TOS value can be specified either as a decimal number or ; as a hex number in the 0xnn format. ; Default value: 0xb8 ; ; idleTimeout Expire idle sessions after this much time. ; Default 60 seconds ; ; holdTimeout Expire calls on hold after this much time. ; Default value is 3600 seconds ; ; forceClose Forcibly close a RTP session after this many seconds even if ; it's still active. If forceClose is 0, then a session is never ; closed no matter how long it lasts. ; Default value: 0 ; start = yes socket = /var/run/mediaproxy.sock group = ser listen = 200.142.103.114 allow = any ;proxyIP = 10.0.0.1 portRange = 35000:36000 ;TOS = 0xb8 idleTimeout = 60 holdTimeout = 3600 forceClose = 0 accounting = off
