Email and Groupware / accessing SOGo behind reverse proxy

« on: February 12, 2019, 10:39:56 pm »

I have nginx running as my reverse proxy, and when I access the SOGo webpage behind it, there is no static content (css). I can see the text on the page with the login input fields, but there is no way to submit the form.

Has anyone else ran into this, and how did you fix it?

Thanks,

Installation and Upgrades / Where should this sit on my network?

« on: January 22, 2019, 02:57:20 pm »

I am debating on whether this should sit on my LAN or DMZ. LAN because I want easy file sharing, and active directory. DMZ because I need to expose the email server...
I only have one available public IP address so I am wondering if pointing mail.mydomain.com to this email server is even possible. I have a pfsense router. Any insight or help on this is appreciated.

Other modules / dns, dhcp, and email configuration

« on: January 13, 2019, 04:30:48 pm »

Hello, I have a pfsense edge router that I am using for firewall and dhcp server. I just installed a Zentyal server behind my edge router. Here are some of my configuration.

pfSense - dns pointed to the Zentyal server. Setup so that the clients get the zentyal server as the dns server. DNS resolver on pfSense is enabled.
zentyal dns - forwarders configured for external network servers (OpenDNS). I've added some known host ip addresses on the domain. These are reserved ips in the pfsense router.

It seems like I am putting the DNS resolution in a semi-circle here. Here are things that are not working:
1. The only hosts that are resolving are the known domain hosts. I should note that external DNS resolution is working (google.com).
2. My domain name is not being resolved when a client tries to connect on a web browser on a specific port. I've verified that the port is open and being forwarded in the edge router. For example, trying to connect to "https://<mydomain>.com" works when connected to an external network, but it times out when connected to the internal network.

Things I've tried:
1. I've tried adding my edge router as a DNS forwarder in the Zentyal server. This did not change things.
2. I've tried turning my DNS resolver off on the edge router.
3. If I remove a known host in Zentyal domain - the host no longer resolves.

What's the best practice here? Do I have to go through my edge router for DNS resolution? I wouldn't think so, but the DHCP leases are not registering with the Zentyal server - so something is broken.

This issue affects email. I try to configure my clients to use <mydomain.com> for incoming mail and it times out at setup.
Any direction or help is greatly appreciated.

thanks!
