I could not make tpws work from ipfw. Looks like there's some conflict between two firewalls.
|
||||||
|
Only PF redirection works. PF does not allow to freely add and delete rules. Only anchors can be reloaded.
|
||||||
|
To make an anchor work it must be referred from the main ruleset. But its managed by pfsense scripts.
|
||||||
|
One possible solution would be to modify '/etc/inc/filter.inc' as follows :
|
||||||
|
```
|
||||||
|
$natrules .= "# TFTP proxy\n";
|
||||||
|
|
||||||
|
/* MOD */
|
||||||
|
$natrules .= "rdr-anchor \"zapret/*\"\n";
|
||||||
|
|
||||||
|
$natrules .= "rdr-anchor \"tftp-proxy/*\"\n";
|
||||||
|
```
|
||||||
|
|
||||||
|
Write the anchor code to '/etc/zapret.anchor':
|
||||||
|
```
|
||||||
|
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||||
|
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::20c:29ff:5ae3:4821 port 988
|
||||||
|
```
|
||||||
|
|
||||||
|
Autostart '/usr/local/etc/rc.d/zapret.sh' :
|
||||||
|
```
|
||||||
|
pfctl -a zapret -f /etc/zapret.anchor
|
||||||
|
pkill ^tpws_pf$
|
||||||
|
tpws_pf --daemon --port=988 --split-http-req=method --split-pos=2
|
||||||
|
```
|
||||||
|
|
||||||
|
Note that the special tpws version is used which supports PF.
|
||||||
|
After reboot check that anchor is created and referred from the main ruleset :
|
||||||
|
```
|
||||||
|

Что касается tpws, то видимо имеется некоторый конфликт двух фаерволов, и правила fwd в ipfw не работают.
|
||||||
|
Работает перенаправление средствами pf как описано в разделе по FreeBSD.
|
||||||
|
В pf можно изменять правила только целыми блоками - якорями (anchors). Нельзя просто так добавить или удалить что-то.
|
||||||
|
Но чтобы какой-то anchor был обработан, на него должна быть ссылка из основного набора правил.
|
||||||
|
Его трогать нельзя, иначе порушится весь фаервол.
|
||||||
|
Поэтому придется править код скриптов pfsense. Поправьте /etc/inc/filter.inc следующим образом :
|
||||||
|
-----------
|
||||||
|
$natrules .= "# TFTP proxy\n";
|
||||||
|
|
||||||
|
/* MOD */
|
||||||
|
$natrules .= "rdr-anchor \"zapret/*\"\n";
|
||||||
|
|
||||||
|
$natrules .= "rdr-anchor \"tftp-proxy/*\"\n";
|
||||||
|
-----------
|
||||||
|
|
||||||
|
Напишите файл с содержимым anchor-а (например, /etc/zapret.anchor):
|
||||||
|
-----------
|
||||||
|
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||||
|
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::20c:29ff:5ae3:4821 port 988
|
||||||
|
-----------
|
||||||
|
|
||||||
|
Добавьте в автозапуск /usr/local/etc/rc.d/zapret.sh :
|
||||||
|
-----------
|
||||||
|
pfctl -a zapret -f /etc/zapret.anchor
|
||||||
|
pkill ^tpws_pf$
|
||||||
|
tpws_pf --daemon --port=988 --split-http-req=method --split-pos=2
|
||||||
|
-----------
|
||||||
|
|
||||||
|
Обратите внимание, что запускается специальная версия tpws с поддежкой pf. Обычный tpws не работает с PF.
|
||||||
|
После перезагрузки проверьте, что правила создались :
|
||||||
|
-----------
|
||||||
|

|
||||||
|
