configuring LTM VE in network

Hi, I want to ask regarding ltm ve configuration for using in network

 

 

I try to setup big-ip with host only adapter for mgmt port and using 1 vlan 1.1 setup at bridge mode. By doing this I manage to have setting up virtual server in within the subnet 255.0.0.0. But by using this I can't access big-ip from another machine.

 

 

I have created an application to control big-ip like setting up virtual servers, rules, etc in a server. So I need big-ip to be accessible from another machine. Anyone can tell me how to do that? Because when I try to set big-ip mgmt to bridge mode and use ip address on the same subnet, i cannot assign ip address as it has the same subnet with mgmt ip address.

 

 

for information,

 

IP address for server which have application to control big-ip is 202.172.230.136

 

Virtual Server 10.0.0.12

 

1.1 VLAN self ip 10.0.0.3

 

machine which running

 

all above within the subnet 255.0.0.0

 

LTM VE mgmt ip 192.168.138.128

    Hi Fiko,

     

     

    If you only have one network that's reachable off the host, I'd set the mgmt port to use a host only adapter and use a self IP to administer the VE instance remotely. You can then define virtual servers on the same subnet as the self IP.

    You can use a browser to go to https://10.0.0.3 or an SSH client like Putty to get to the command line. For console access you can use your hypervisor's virtual console.

    thanks Aaron for your help, its working by now

     

     

    but I got another problem when connecting to pool member 202.172.230.136 which has the same address with the application server. Status said its unavailable.

     

     

    when I try to ping from console it didn't get any replies. Is it because its in different subnet with LTM VE so I cannot use it as pool member? Is there any way to make 202.172.230.136 as pool member?

    You'll need a route to hosts on a different subnet than the self IP address. You can configure a TMM route via the GUI under Network >> Routes. Once you have a route, you can configure a remote host as a pool member. You'll want to use SNAT (automap or a SNAT pool) on the virtual server to ensure responses come back to the client via LTM.

    hi Aaron

     

     

    I don't know how to configure TMM route but I set up default gateway in Routes and use VLAN as resource now can connect from different subnet. But when configuring pool member, I already set SNAT to automap but when I access virtual server ip, I cannot get response from the server (server not found). How to resolve this?

    A default gateway in the routes section of the GUI is a TMM route. Can you change it from a VLAN to an actual gateway IP address and retest?

    OK change to gateway IP address now can load balance from Pool
