  • 1.  Adding secondary ip range on untrust with DIP - not possible if not in same subnet?

    Posted 07-28-2010 07:35

    Hi,

     

    I've been searching for hours now but cannot find it.

     

    This is my config i got from my provider:

    There router = 213.224.XX.125/30

    My ethernet0./0 (untrust) is = 213.224.XX.126/30

     

    I have a default route is set to 125 and the internet works.  So far so good.

     

    Now i have a second ip range with 16 usable ipranges 84.199.XX.128/28

    Now i need to make a DIP for address 84.199.XX.129 and use a policy that does source translation for sip traffic on the 129 address.

     

    Now when i try to add this DIP entry on the untrust it gives me a message that the Dynamic ipmust be in the same subnet.

    Hency my problem. 

     

    My question: how can i add this second range to my untrust side knowing that i cannot use a MIP for the 84.199.XX.129 address because i have some phones on the trust interface (5 of them) that go to an outside SIP server.

     

    So i need to make a policy for SIP traffic that does source routing on that DIP.

     

    Can anyone help me with this please?

    Hi!

     

    I think this command will solve your problem:

     

    set interface ethernet0/0 ext ip 84.199.xxx.128/28 dip <dip pool number> 84.199.xxx.129 84.199.xxx.142

     

    The keywords here are "ext ip" - extended ip.

     

    Kind regards,

    Edouard
