Mit diesem Addon kann man über das Webinterface bestimmten Rechnern im LAN eine bestimmte abgehende Ip zuweisen.

Voraussetzung:
Es werden mehrere rote Ipadressen (Aliase) verwendet.


Installation:

Die Datei auf den Ipcop kopieren, mit

tar xfz snatgui_ipcop_1.4.13.tar.gz

entpacken.

Dann ins Verzeichniss snatgui wechseln und

./install

aufrufen.

Nach dem Installieren bitte das Verzeichniss snatgui wieder
verlassen da es vom Installationsskript gelöscht wird.

Nun kann man über das Webinterface unter Firewall=>SNAT bequem
einstellen, welcher Host mit welchem Alias ins Internet geht.

Zum Deinstallieren einfach

/var/ipcop/snat/bin/uninstall

aufrufen.






With this addon you could easily configure which alias-ip
a host should use to connect ot the internet.

It will only work if you have configured aliases for red.

Installation:

copy the file to your ipcop, extract with

tar xfz snatgui_ipcop_1.4.13.tar.gz

then enter the snatgui-directory and run

./install

and then leave the snatgui-directory because the install-script has
deleted it.

Now you could configure SNAT from the Webinterinterface
under firewall=>SNAT.

Uninstall:

Just run

/var/ipcop/snat/bin/uninstall

Hi,

I've just installed the addon on IPCop 1.4.13 and I've noticed two small but critical problems:

- The green IP on eth0 (172.26.5.254) has an alias (172.26.3.254) which isn't recognized. This effectively blocks outgoing traffic from the 172.26.3.0/24 network since no SNAT or Masq is performed on packets. FYI: this alias isn't configured in the IPCop webinterface (because it doesn't support aliases on the green network), it's a manual hack. The only way to find this alias is by parsing the output of 'ifconfig', which is doable.

- For some reason 'generic' traffic from my green network (traffic from hosts which haven't got an external SNAT address and should get the IPCop red address assigned) isn't picked up by the generic 172.26.5.0/24 rule. This can be solved by removing the restriction on the input interface of this rule, which is specified by the '-i' parameter on lines 273 and 459 of the setsnat-script. I can't think of a reason why this won't work, but it does work without the '-i' option. Furthermore I don't think there are any security issues introduced by removing the '-i' option, so why not remove it?

Can you please address those issues?

Markus,

I am running IPCop v.14.16 and have installed your latest version SnatGUI (1.9.2) but it does not work as expected. The static NAT does not work for the ORANGE zone IP address but works for GREEN zone IP address.

FYI... my IPCop box is having GREEN, RED, ORANGE and BLUE networks.

GREEN: 10.250.1.0/24
BLUE: 10.250.2.0/24
ORANGE: 10.250.3.0/24
RED: .71 - .75.

The web server is inaccessbile when setting 10.250.3.10 => .72 does not work. I move the machine to GREEN with IP 10.250.1.130 and set => .72, it works. The web server can be reached from public.

Could you please advise what went wrong?

I have seen several postings about this problem. Removing/disabling ORANGE NIC or moving the maching to GREEN zone solve the problems. But again this defies the functions, controls and purposes of DMZ (ORANGE zone).

Please advise... Thanks...

Is there a upgrade procedure from 1.9 to 1.9.2 or do we just have to uninstall and reinstall the add-on?

Thanks for the great work.
Thomas

Just install the new version, the install-script will update the previous version.

I think a found a bug:

We did a upgrade from snatgui_ipcop_1.4.11.tar.gz to snatgui_ipcop_1.4.13.tar.gz and the strange behaviour is:

If a NAT rule is defined, then anyhting works fine. If for a particular host is no NAT-Rule defined - and so the default public IP of IPCop should be used, then the request cant pass the firewall. And there are also no error messages in /var/log/message.

Greetings, Markus.

I had some problems with my mail-server, but then I found your addon and it seemed that my problemes were solved. But now I see, that when SNAT is started ICQ can't connect to server and I can't open hotmail.com... When I stop SNAT everything works fine...
I have proxy sever on and think that problem is in "Traffic control&report" addon, but I'm not sure.

I have installed the latest snatgui and when I start it, I lose my Green. Noting on the LAN can get out to the Internet... I have created a port forward and disabled it but that did not seem to help. I have a web/mail/ftp server on my Orange and I need to get this working for my mail server. Any other ideas?
