Re: [Serusers] SER and NAT

Hello Adrian, Thanks for your answers. They were very clarifying. I test in my lab test environment where i do not have any firewalls or other possible problem initiators. The ser.cfg example that comes with the source with mediaproxy does not allow non nated EP's to register. Is it possible for you to update the example config file so non nated ep's can also register and do not use mediaproxy when traffic is between non nated ep's. NATed -- NATed mediaproxy Public C -- NATed mediaproxy. Public C -- Public C no mediaproxy. Please just hint me in the correct direction. Here is my current ser.cfg It is not working the way i want like mentioned above. . # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode debug=7 fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #port=5060 #children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/textops.so" loadmodule "/usr/local/lib/ser/modules/domain.so" loadmodule "/usr/local/lib/ser/modules/mediaproxy.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #loadmodule "/usr/local/lib/ser/modules/auth.so" #loadmodule "/usr/local/lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- #modparam("usrloc", "db_mode", 0) #modparam("domain", "db_url", "sql:ser:heslo@localhost/ser") //now using default # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line #modparam("usrloc", "db_mode", 1) # -- auth params -- # Uncomment if you are using auth module # #modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # #modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic modparam("mediaproxy", "natping_interval", 60) route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too many hops"); break; }; if (msg:len >= max_len) { sl_send_reply("513", "Message too big"); break; }; if (client_nat_test("3")) { if (method == "REGISTER" || ! search("^Record-Route:")) { fix_contact(); force_rport(); }; if (method=="INVITE") { use_media_proxy(); t_on_reply("1"); }; }; if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("200.84.12.12", "subscriber")) { # www_challenge("200.84.12.12", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; if (method == "BYE" || method == "CANCEL") { end_media_session(); }; if (loose_route()) { t_relay(); break; }; if (method == "INVITE") { record_route(); }; if (!t_relay()) { sl_reply_error(); }; } onreply_route[1] { if (status=~"(183)|2[0-9][0-9]") { if (client_nat_test("1")) { fix_contact(); }; use_media_proxy(); }; if (status=~"[3-4]0[0-9]") { end_media_session(); break; }; } On Fri, 2004-06-04 at 00:48, Adrian Georgescu wrote:
