Ok, I tested and it is working but I would kindly need an explanation

1- the setup :=20
- kamailio 5.1 with three listen (on port 5060, 5063, 5066)
- 2 UAs using UDP on port 5063
- added a log in the script


```
route[WITHINDLG] {
        if (!has_totag()) return;

        # sequential request withing a dialog should
        # take the path determined by record-routing
        if (loose_route()) {
                route(DLGURI);
                if (is_method("BYE")) {
                        setflag(FLT_ACC); # do accounting ...
                        setflag(FLT_ACCFAILED); # ... even if the transaction=
 fails
                } else if ( is_method("ACK") ) {
                        # ACK is forwarded statelessly
                        xlog("forced socket $fs\n");
                        route(NATMANAGE);
                } else if ( is_method("NOTIFY") ) {
                        # Add Record-Route for in-dialog NOTIFY as per RFC 66=
65.
                        record_route();
                }
                route(RELAY);

```

2- parameter for rr module

```
modparam("rr", "enable_full_lr", 0)
modparam("rr", "enable_double_rr", 1)

```

3- result - on K master, ACK gets forwarded  **properly** using source port 5=
036 with the following traces

```
