TMG:Change Management IP Address
This article explains how to modify the management network interface of TMG800, TMG3200, and TMG7800-CTRL (MGMT0), and the control ports of the TMG7800-CTRL (ETH0, ETH1).
By default, all Tmedia management ports (MGMT0 for the TMG800, TMG3200, TMG7800-CTRL, and ETH0 and ETH1 for the TMG7800-CTRL) are configured as DHCP. To modify this default setting, the Tmedia is accessed through the serial port. See section '5.1 Connecting to the Serial Port' of the product installation guides for further information.
To avoid modification of the configuration files using 'vim' or 'nano', which is not very user friendly; TelcoBridges created a shell script to simplify the network configuration of the Tmedia.
The script will allow you to:
- Change the IP address of the MGMT0 port, and ETH0 and ETH1 ports (for TMG7800-CTRL)
- Change the default network interface and IP address
- Change the DNS
WARNING: Remember to restart Toolpack after you change the IP address.

Modify static IP address
This example changes the IP address to a static address with no DNS server
- Steps to modify mgmt0 from dhcp to static:
Do you want to modify the network settings (enter 'help' for usage) ?[No] --> yes Do you want to modify mgmt0 ?[No] --> yes Select network mode (dhcp or static) ?[dhcp] --> static Enter IP address ?[] --> 10.0.0.126 Enter network mask ?[] --> 255.255.255.0
- Steps to modify the default gateway address (this is necessary to assign an IP address when in static mode.)
Would you like to modify the default gateway address ?[No] --> yes Enter default gateway ip address ?[] --> 10.0.0.1
- Steps to remove the DNS configuration
Would you like to modify the DNS configuration ?[No] --> yes Would you like to reconfigure the DNS (enter 'remove' to erase dns) ?[No] --> remove
- The script will show you the new configuration. Then you can acknowledge the changes.
Do you want to save this new configuration ?[No] --> yes
- You can ask the script to restart the network service and apply the new configuration.
Would you like to restart the network service now ?[No] --> yes
- Toolpack needs to be restarted to be aware of the change
tbtoolpack restart
Change dhcp to static
This example changes the IP address from DHCP to a static IP with no DNS server
- Steps to modify mgmt0 from dhcp to static:
Do you want to modify the network settings (enter 'help' for usage) ?[No] --> yes Do you want to modify mgmt0 ?[No] --> yes Select network mode (dhcp or static) ?[dhcp] --> static Enter IP address ?[] --> 192.168.0.40 Enter network mask ?[] --> 255.255.255.0
- Steps to modify the default gateway address (this is necessary to assign an IP address when in static mode.)
Would you like to modify the default gateway address ?[No] --> yes Enter default gateway ip address ?[] --> 192.168.0.1
- Steps to remove the DNS configuration
Would you like to modify the DNS configuration ?[No] --> yes Would you like to reconfigure the DNS (enter 'remove' to erase dns) ?[No] --> remove
- The script will show you the new configuration. Then you can acknowledge the changes.
Do you want to save this new configuration ?[No] --> yes
- You can ask the script to restart the network service and apply the new configuration.
Would you like to restart the network service now ?[No] --> yes
- Toolpack needs to be restarted to be aware of the change
tbtoolpack restart
Change static to dhcp
This example changes the IP address from static to DHCP IP with a DNS server (1 domain and 2 nameservers)
- Steps to modify mgmt0 from static to dhcp:
Do you want to modify the network settings (enter 'help' for usage) ?[No] --> yes Do you want to modify mgmt0 ?[No] --> yes Select network mode (dhcp or static) ?[static] --> dhcp Select a dhcp name ?[TB006201] --> TB006201
- Steps to modify the default gateway address (you should let the DHCP server give you the gateway address)
Would you like to modify the default gateway address ?[No] --> yes Which network interface do you want to set as default gateway address interface (mgmt0/mgmt1) --> mgmt0 Select the host dhcp name ?[TB006201] --> TB006201
- Steps to configure the DNS (this example will set up 1 search domain and 2 nameservers)
Would you like to modify the DNS configuration ?[No] --> yes Would you like to reconfigure the DNS (enter 'remove' to erase dns) ?[No] --> yes First search domain (enter 'remove' to remove entry) ?[] --> mynetwork.lan Second search domain (enter 'remove' to remove entry) ?[] --> First nameserver ip address (enter 'remove' to remove entry) ?[] --> 192.168.0.10 Second nameserver ip address (enter 'remove' to remove entry) ?[] --> 192.168.0.11 Third nameserver ip address (enter 'remove' to remove entry) ?[] -->
- The script will show you the new configuration. Then you can acknowledge the changes.
Do you want to save this new configuration ?[No] --> yes
- You can ask the script to restart the network service and apply the new configuration.
Would you like to restart the network service now ?[No] --> yes
- Toolpack needs to be restarted to be aware of the change

NOTE: The networks 172.31.1.x (netmask 255.255.255.0) and 172.16.x.x and 172.18.x.x (netmask 255.255.0.0) cannot be used for the management Interface IP because they are reserved for internal use.
