How to change the ip address
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
NOTE 1: you need to remove the line DHCP_HOSTNAME
NOTE 2: int0/vlan3/eth1 interface must remain 172.31.1.2
Example:
Add the default gateway address in the network configuration file
Example:
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).
Example of a DNS configuration file without DNS server:
Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly):
Restart the network interfaces
Switch from static to DHCP
Modify the mgmt0 (or eth0) configuration
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:
Remove the default gateway address in the network configuration file
Example:
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).
