Installation and Upgrades / Ethernet card Not detecting Issue

« on: June 13, 2016, 07:43:03 am »

Hi,

I have a Zentyal 4.2 system and it has 2 ethernet cards. One system configured as eth0 for outgoing internet connection and other as eth1 for internal connections. eth0 - 192.168.1.150 and eth1 as 10.1.1.150 .
eth1 is acting as DHCP server and serving the IP range of 10.1.1.200 to 10.1.1.250 as range with ip 10.1.1.1 configured as gateway .

The problem is the eth1 is not getting detected many times when rebooting and it always switches on eth0 and eth1 not getting recognized. Sometimes even when eth1 is recognized the DHCP range will dissappear. I have to reboot the server twice or thrice and then the eth1 detects or i will manually configure eth1 as 10.1.1.150 and reconfigure DHCP ranges so that clients in LAN will work from web console.

I have tried replacing 2 ethernet cards but this problem arises every other day.

Configuration of /etc/network/interfaces

auto lo eth0 eth1

iface lo inet loopback

iface eth0 inet static
  address 192.168.1.150
  netmask 255.255.255.0
  broadcast 192.168.1.255

iface eth1 inet static
  address 10.1.1.150
  netmask 255.255.255.0
  broadcast 10.1.1.255

Can someone help how to fix this issue.

Best Regards,

Hi,

We have configured Zentyal Development edition as AD,Fileserver,DHCP,DNS server and HTTP proxy server as well.

With external interface is eth0 (IP -192.168.1.50, subnet mask - 255.255.255.0,gateway - 192.168.1.1).This is connected to our ISP Router 192.168.1.1 (which acts as external).
The LAN interface eth1 is configured as 10.1.1.50,subnet mask 255.255.255.0) and DNS forwarder is 10.1.1.1.
This system is not using mailserver or mail filter. Server configuration as stated below.

DNS
------
DNS forwarder - 10.1.1.1
Domains - test.lan
Domain IP Addres - 10.1.1.150 and 192.168.1.150
Nameservers - server01
Transparent cache enabled

DHCP
--------
eth0 disabled
eth1 Enabled (10.1.1.150)
Default Gateway - Custom IP Address: 10.1.1.1
Search domain - Custom - test.lan
Primary Nameserver - local Zentyal DNS
Secondary nameserver - 10.1.1.150 (server eth1 IP)
NTP Server - local Zentyal NTP
Dynamic DNS Option - Enabled
Dynamic Domain - test.lan
DHCP Range - IP :10.1.1.150, Subnet 10.1.1.0/24, Available Rane - 10.1.1.1-10.1.1.254

Packet Filter - Internal networks to Zentyal
--------------------------------------------------------
Any - SMTP TCP port 25 ,Incoming Mail TCP ports (POP TCP - 110,143,995,995,4190)  ,Mail Submission( 587,465),Printers,DHCP,TFTP,Samba,DNS,NTP Enabled

Packet Filter-> Internal networks

External Networks to Zentyal
----------------------------
Source - Any for services - Any, Incoming Mail,SMTP,Mail submission.

Traffic coming out from Zentyal
--------------------------------
Destination - Any for service - Mail submission,SMTP,Incoming Mail,Any Service.

Currently AD works, Samba works, Proxy works and users in 10.1.1.200 LAN are able to do everything.

Problem is from 10.1.1.0 LAN, nobody is able to use email clients and download mail using POP 110 port and send mail via SMTP 25 port

This server is not configured for Mail Filter,Mail and Groupware and OpenChange Server. Currently external mails need to be downloaded via this server.

From 10.1.1.0 subnet, not able to telnet to port 110 or 25.

Can someone help how to get this done. IPtables -L details attached in the attachment.
