How to Access DSL modem in Front of UTM?

JohnRiley

Hi everyone, racking my brain on this one.

I'm running MLPPP with 2 x DSL modems.   I have each modem plugged into an interface on the UTM.   So only have 3 ports running, 1 x Internal and 2 x modem facing (single logical MLPPP).

I know each modem is configured for 192.168.x.1 /24.  Modem 1 is 1.1, and Modem 2 is 2.1.

My internal network is a 10's address.

I'm trying to be able to access the 192.xxx modems from my 10's network.   

Since UTM's implementation of MLPPP is, well weird (In the other 2 firewalls I tried you create 2 ethernet ports with IP addresses etc., then you ADD PPPoE/MLPPP to those ports - easy!).  I can't find a way to access these modems without either 1) disconnecting them and plugging them directly into a laptop, or 2) getting another switch to plug all the modems and UTM WAN interfaces into just to 'fudge' getting access to the modems.

I tried using "Additional Addresses" on the MLPPP interface, but no joy.

Any help would be greatly appreciated!

    Hi everyone, found work around:

    Enable SSH on UTM, and hit the command line
    Find the interfaces in question "ifconfig"
    Then assign the interfaces the addresses manually.

    I have 1 modem @ 192.168.1.1, and the other @ 192.168.2.1.
    So 2 commands on the appropriate facing interfaces:
    "ifconfig INTERFACE 192.168.2.2 netmask 255.255.255.0"
    "ifconfig INTERFACE 192.168.1.2 netmask 255.255.255.0 "

    Where "INTERFACE" is your eth interface facing the modem(s)
    That did the Trick! Modems are now accessible internally.
