  • 1.  Source NAT Many to One

    Posted 07-13-2011 07:50

    Hello,

    I'd like ton create a source NAT config that use another IP than the interface IP. Is it possible to do so?

     

    Local LAN (192.168.1.0/24) ----- SRX (1.1.1.1/24) ------- Internet

     

    Is it possible to NAT the Local LAN with IP 1.1.1.2 for example?

     

    set security nat source pool MyPool address 1.1.1.2/32 to 1.1.1.2/32
    set security nat source rule-set RL1 from zone trust
    set security nat source rule-set RL1 to zone untrust
    set security nat source rule-set RL1 rule NATLAN match source-address 192.168.1.0/24
    set security nat source rule-set RL1 rule NATLAN then source-nat pool MyPool

     

    does this looks corect?

    do I need Proxy ARP as well on the external interface?

     

    Thank you

    Hi

     

    One address in pool - will be working, no problem.

    And yes, you need proxy arp in such case.
