This article will explain how to manually change the management IP address of TMG800/TMG3200/TMG7800 of the Linux host.

On TMG800 and TMG3200 units you can have up to four internal interfaces:

  • pre-2011:
    • TMG800 -> Management Interface: eth0, Internal Interface: eth1
    • TMG3200-> Management Interface: eth0, Internal Interface: eth1
  • 2011 and after:
    • TMG800 -> Management Interface: mgmt0, Internal Interface: vlan3, 1+1 interface#1: vlan710, 1+1 interface#2: vlan711
    • TMG3200-> Management Interface: mgmt0, Internal Interface: int0, 1+1 interface#1: vlan710, 1+1 interface#2: vlan711

NOTE 1: Only the eth0/mgmt0 network interface should be changed, int0/vlan3/eth1 should stay at 172.31.1.2 since it is directly connected to the Tmedia base board and 1+1 vlans are configured with the Host role (see Tmedia 1+1).

NOTE 2: The network 172.31.1.x (netmask 255.255.255.0) cannot be used for the management IP.


On TMG7800-CTRL servers, you have three internal interfaces:

  • pre-2011:
    • TMG7800-> Management Interface: eth0, Internal Interface#1: eth1, Internal Interface#2: eth2
  • 2011 and after:
    • TMG7800-> Management Interface: mgmt0, Internal Interface#1: eth0, Internal Interface#2: eth1

NOTE 1: Only the eth0/mgmt0 network interface should be changed. eth1/eth0 will use the default address for primary (172.16.0.1) or secondary (172.16.0.2). eth2/eth1 will use the default address for primary (172.18.0.1) or secondary (172.18.0.2). (see Tmedia 1+1).

NOTE 2: The networks 172.16.x.x and 172.18.x.x (netmask 255.255.0.0) cannot be used for the management Interface IP.


Switch from DHCP to static

Modify the mgmt0 (or eth0) configuration 

   vi /etc/sysconfig/network-scripts/ifcfg-mgmt0

NOTE 1: you need to remove the line DHCP_HOSTNAME

NOTE 2: int0/vlan3/eth1 interface must remain 172.31.1.2

Example: 
   DEVICE=mgmt0
   BOOTPROTO=static
   IPADDR=192.168.1.10
   NETMASK=255.255.255.0
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes

Add the default gateway address in the network configuration file 

   vi /etc/sysconfig/network
Example: 
   HOSTNAME=TB005376
   NETWORKING=yes
   GATEWAY=192.168.1.1


Modify the DHCP client configuration.

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS). 

   vi /etc/resolv.conf
Example of a DNS configuration file without DNS server: 
   ; generated by /sbin/dhclient-script


Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly): 
   ; generated by /sbin/dhclient-script
   nameserver 4.2.2.2
Restart the network interfaces: 
   /etc/init.d/network restart

Switch from static to DHCP

Modify the mgmt0 (or eth0) configuration 

   vi /etc/sysconfig/network-scripts/ifcfg-mgmt0

NOTE 1: you need to remove the IPADDR and NETMASK lines

NOTE 2: int0/vlan3/eth1 interface must remain static at 172.31.1.2

Example: 
   DEVICE=mgmt0
   BOOTPROTO=dhcp
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes
   DHCP_HOSTNAME=TB005376

Remove the default gateway address in the network configuration file 

   vi /etc/sysconfig/network
Example: 
   HOSTNAME=TB005376
   NETWORKING=yes

Modify the dhcp client configuration.

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS). 

   vi /etc/resolv.conf
Example of a DNS configuration file without DNS server: 
   ; generated by /sbin/dhclient-script


Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly): 
   ; generated by /sbin/dhclient-script
   nameserver 192.168.1.5
