Hi all, First ping_nated_only param of nathelper is unusable. and nathelper function is_nated? is unusable too. I used testing src_ip of NAT address instead of it. natping function is no effect for cisco route(cisco 2622 with ios 12.2T)? I used the function but fail at last. The NAT mirror lost at last. I only can use register in 900 seconds. And I even don't know if it's useful.

Hi all,
Yes, I am trying to do it but late. Because the system is in working and I can't stop it. Today I only finished preparing a testing system.

Wangji,
Not sure, but normally you need to force_rport
and
fix_nated_contact at registration, before you save to DB.

Hi all, The problem is I can't register two SIP
UAs
to
SER server.
This is my environment: Internet | router (X.X.X.163) | |Fiber |---- Ser server
(X.X.X.166)
| |Switch------|---- Trunk Gateway
(X.X.X.167)

Users SIP UA1(172.16.2.11) SIPUA2(172.16.2.23)
My ser.cfg like: route{ if ( msg:len > max_len ) {
sl_send_reply("513","Message
too
big"); break; }; record_route(); if (loose_route()) { t_relay(); break; };
if (!method=="BYE") { force_rport(); fix_nated_contact(); };
if (method=="REGISTER") { if(!www_authorize("novsky.com",
"subscriber")) {
www_challenge("novsky.com",
"1"); break; }; save("location"); break; };
if (method=="INVITE") {if(!proxy_authorize("novsky.com","subscriber")) {
proxy_challenge("novsky.com","1"); break; }; };
if(uri=~"^sip:6169[0-9]*@[0-9|.]*")
{
if(!lookup("location")) {sl_send_reply("404",
"Not
Found"); break; }; }else { forward(172.16.255.2,6050); break; }; if (!t_relay()) { sl_reply_error(); }; } I use ethereal to look the packet, first UA1
send
REGISTER to SER server, on NAT it use 5060
port,
and
SER return to corrent address/port. When UA2 send REGISTER to SER server, on NAT
it
use
1027 port, but SER return to NAT:5060 port
and
the
packet transfered to UA1. So UA2 can't register. I can see the NAT table on route, like udp x.x.x.165:5060 172.16.2.11:5060
x.x.x.165:5060
x.x.x.x.165:5060 udp x.x.x.165:5060 172.16.2.23:5060
x.x.x.165:1025
x.x.x.x.165:1025
