Hi everyone !
One of my client have a srx100 Juniper and i meet a problem for replace a static NAT.
To the juniper, a technician have create a static NAT 2 years ago (in the menu NAT → Static NAT) . The technician have NAT a WAN public address to a LAN private address.
The technician have create this static NAT : WAN address: 185.46.95.125 → LAN address 192.168.1.10 (SRV-02).
This static NAT permit to ping and to have access to the 185.46.95.125.
Today, i would like to replace this static NAT by this :
WAN address: 185.46.95.125 → LAN address 192.168.1.20 (SRV-02).
But when i try to modify this static NAT, my Wan PC wont to ping and have access to the 185.46.95.125.
I have copy and apply the sames policy of the SRV-01 for the new SRV-02.
Thank you for your help.
