### Description

I enabled mhomed=1 as well as ip_free_bind=1, but kamailio does not recognize that there is internal and external traffic.
For example I also enabled modparam("rr", "enable_double_rr", 1), but the 2 Record-Routes both have the external IP.
In addition fix_nated_contact() and fix_nated_sdp don't work because they think all traffic is coming from the external IP.
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->

### Troubleshooting
I tried a lot of things.

#### Reproduction
Set up a server with keepalived and a virtual IP and use any standard NAT config and it won't work.

<!--
If the issue can be reproduced, describe how it can be done.
-->

#### Debugging Data

<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.

  gdb /path/to/kamailio /path/to/corefile
  bt full
  info locals
  list

If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

```

#### Log Messages

<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).
-->

```
(paste your log messages here)
```

#### SIP Traffic

<!--
If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).
-->

```
(paste your sip traffic here)
```

### Possible Solutions
I thought that ip_free_bind=1 would fix this issue, but it does not seem to have any effect.

<!--
If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix.

### Additional Information

  * **Kamailio Version** - output of `kamailio -v`

```
(paste your output here)
