Can anyone explain me the difference between proxy-arp or a address assigned to a interface?
I hava a SRX 300 connected to a /28 subnet
I want to 1:1 nat some adresses to the inside
The GE-0/0/0.0 interface has an address of 22.214.171.124/28
The GE-0/0/5.0 interface has an address of 192.168.1.2/24
For example i 1:1 nat the following 2 addresses 126.96.36.199 <-> 192.168.1.2
Now i have 2 options.
1) Proxy-Arp 188.8.131.52 on interface GE-0/0/0.0
2) Add address 184.108.40.206 on interface GE-0/0/0.0
Both options works but what is technically the difference between those 2 ?
Here is good example of when to configure Proxy ARP:
and the interface address add would be more of static approach
