Re: No ping Proxy-ARP from LAN/DMZ

Hello,

I checked this link https://kb.juniper.net/InfoCenter/index?page=content&id=KB21785&actp=search and now i have more details for this problem :

>show security nat proxy-arp
interface ge-0/0/0.0 {
    address {
        XXX.XX.XX.91/32;
        XXX.XX.XX.93/32;
        XXX.XX.XX.94/32;
        XXX.XX.XX.92/32;
    }
}

But i can't ping these IP from firewall : 

> ping XXX.XX.XX.92
PING  XXX.XX.XX.92 ( XXX.XX.XX.92): 56 data bytes
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address

When i checked route : 

> run show route XXX.XX.XX.92 extensive

inet.0: 30 destinations, 30 routes (30 active, 0 holddown, 0 hidden)
XXX.XX.XX.92/32 (1 entry, 1 announced)

This is very strange... SRX don't see these IP.

Have you an idea ? 

Thank your for your help.

Best regards.
