Dear all,

I need your help, I am configuring shorewall with FTP and Web Server behind the shorewall box. The topolgy is

Internet======>Shorewall====>Switch====>FTP,WEBSERVER,PROXY=====>LAN

The shorewall has 2 ethernet with public IP:
eth0 = 200.x.x.1
eth1 = 200.x.x.2
eth1:1 = 60.x.x.1

The FTP has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 60.x.x.2
eth1 = 192.x.x.2

The WEBServer has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 60.x.x.3
eth1 = 192.x.x.3

The PROXY has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 202.x.x.3
eth1 = 192.x.x.4


But I have problem with connection to FTP and WebServer.. But the internet connection still running..
Here are my shorewall configuration..

I don't know where is the wrong.. Could you help me please...


Thanks,

Let me make sure I understand... connections from the external (internet) to the webserver are being dropped but outbound internet connections are working?

There are two options that come to mind...

Try:
Where xxx is the ip address of your server.

You may need to set a static NAT rule, since traffic is being MASQ through the two interfaces. This would a Shorewall Manual question - that's one I don't know off the top of my head.

Or... possible adjust the policy rule:
You may want to set it to ACCEPT for testing purposes, just to find out if that rule is blocking or not. If ACCEPT works, and the first suggestion doesn't help... then I would try setting a static NAT rule to the server in question.

hope that helps

I've tried your methode but still doesn't work..

Is there any suggestion...???

Or Do I have to use 1 more interface ? Coz I have different public ip (200.x.x.x and 60.x.x.x.x)

Any idea???

Temporarily setting "net all ACCEPT" had no affect? What did you try as far as setting a static NAT rule to your webserver and FTP?

On the Shorewall box you have:
eth0 = 200.x.x.1
eth1 = 200.x.x.2
eth1:1 = 60.x.x.1

Which interfaces are connected to the internet and/or private LAN? It looks like eth0 and eth1 are internet IPs, while your eth1:1 is connected to the private LAN. Is this correct?

Shorewall doesn't recognize virtual interfaces, but you should still be able to segregate your traffic with the policies and rules.

Dear internalkernel,

Yes, no affect...
I've tried like what u said..

on the rules;
ACCEPT net loc:60.x.x.x tcp 80

and the policy;
net all drop

Did u see my topology?

Internet=====>Shorewall====>Switch====>FTP,WEBSERVER,PROXY=====>LAN

It is mean that the shorewall has no private IP, and the lan doesn't connect directly to shorewall.. the server (FTP,WEB,PROXY) has Private IP to connect directly with LAN and using public IP to connect directly with shorewall box..

The shorewall has 2 ethernet with public IP:
eth0 = 200.x.x.1 (public ip)
eth1 = 200.x.x.2 (public ip)
eth1:1 = 60.x.x.1 (public ip)

The FTP has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 60.x.x.2 (public ip)
eth1 = 192.x.x.2 (private ip/lan)

The WEBServer has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 60.x.x.3 (public ip)
eth1 = 192.x.x.3 (private ip/lan)

The PROXY has 2 ethernet with 1 public ip and 1 more private ip;
eth0 = 202.x.x.3 (public ip)
eth1 = 192.x.x.4 (private ip/lan)

Any idea ??? Should i put 1 more interface for the shorewall box cause it has different public ip on ethernet 1(1:1)...???
