Installation and Upgrades / Zentyal Firewall routing question

« on: June 25, 2012, 03:59:13 am »

I posted this question a few days ago but it does not show up here.

Question. I want to SSH to a machine on dhcp on the internet side of my Zentyal firewall from inside the firewall.
Somehow I am blocked to do this as Zentyal seemingly block the route for ssh to a 192.168.1.0 ip outside the firewall.
The internal ip address I ssh from is on 192.168.0.0

What is the Route I mausrt add in Zentyal firewall to do this, and where must I enter it ?

I already checked that I can ssh between machines on DHCP with the router so the problem does not lie there.

Installation and Upgrades / Firewall Routing

« on: June 20, 2012, 08:18:12 pm »

My network behind firewall is 192.168.1.0
The cable router before the firewall is on network 192.168.0.0 with laptops connecting wirelessly through router to internet.

I want to be able to SSH from my internal network (machine on network 192,168,1,0) to a machine on the router on other side of the firewall connected to the router on network 192.168.0.0.

What rule must I add toe the firewall to effect this?
It used to be easy with usual ipchains way back.

Anyone have an idea what rule needs tpo be added on Zentyal firewall ?

Installation and Upgrades / Zentyal firewall question Port 25

« on: February 09, 2012, 05:56:01 pm »

Comcast silently blocked port 25 and caused an enormous amount of damage to my business as we had no clue why our mailservers stopped working.
They should be sued and really inform customers if they silently block ports.

anyway.

Could anyone tell me how to configure the zentyal firewall to redirect all smtp connections destined for port 25 to e.g. port 587.
Meaning: redirect all outgoing mail configured by postfix or sendmail to be connecting to remote mailserver:25 to mailserver:587
I know it is easy and the firewall config is really veryu nicely done, but I still find the redirects confusing.

Thanks

Installation and Upgrades / accidentally deleted the ebox admin entry

« on: November 09, 2011, 06:35:20 am »

I accidentally deleted the ebox admin entry in the filters setup.
I think it was in the internal to zentyal filters.

So since I removed that I cannot remotely log in by https to the administaration.

Anyone know what the filter entry is to get the acces back ?
Thanks

Installation and Upgrades / Installing software on zentyal

« on: October 31, 2011, 01:56:21 am »

When I installed zentyal it had a nice interface showing all the software I can install.
At that time I selected firewall and nothing else.

Now as I want to install more, there is no way to get back to that interface.
Anyone has a clue how to get to that browser page again?

I copied the browser url at the time, but now it just gives me the control panel and not a page with all the software available.

Installation and Upgrades / Help with making webserver on a third interace (DMZ) visible to internet.

« on: October 31, 2011, 01:34:16 am »

I have a raq550 with Strongbolt and bluequart on a separate interface from my lan as webserver.
My firewall is working great and both lan and a browser on the machine with the webserver can browse the internet through Zentyal firewall.
I forwarded port 80 on the firewall to the webserver address, but the webserver is not visible from the internet.
The webserver works perfectly on it's network in front of the firewall, but I have npo clue what the problem can be as my default gateway of the webserver is set to the zentyal internal interface ip connected to the webserver.

Any ideas what I can look at?

Or, if there is somewhere a complete example with zentyal set up as a firewall for a lan and DMZ on two different network cards with two different networks, I will appreciate it.

Thanks.
