When commit, I got "error: configuration check-out failed"
Below are the current settings:
ge-0/0/1, internet facing, IP:188.8.131.52/27
ge-0/0/2, internal facing, IP:10.10.1.1/24
A FTP server with internal IP:10.10.1.2/24 and prepare to assign 184.108.40.206/27 for its public IP
By following the CLI Quick Configuration in above link. I got below error when commit
[edit security nat proxy-arp interface ge-0/0/1.0]
Proxy ARP IP address range [220.127.116.11 18.104.22.168] overlaps with interface IP address range [22.214.171.124 126.96.36.199] defined on interface 'ge-0/0/1.0'
error: configuration check-out failed
Also it's strange that the boardcast address for .199 is show ".199" instead of ".223"
Are you having one FTP server or a subnet of servers?
If it is a single server(10.10.1.2/32) then you need to set the proxy arp for 188.8.131.52/32 (Just one IP) instead of 184.108.40.206/27. Because the latter would mean device is expected to proxy ARP for whole of the subnet which involves the interface IP as well and this is not required.
