Proxy ARP

L4 Transporter

Hi

 

I have a 5220 in the DC and a 850 in the office

On the 5220 I have an interface onto network 2.7.3.0/24
On the 850 I have a NAT for 2.7.3.129/32
the 5220 get this via OSPF

How can I make the 5220 response on the interface 2.7.3.0/24 for arp requests for 2.7.3.129

Do I have to setup a 1-to-1 NAT on the 5220 so destination nat of 2.7.3.129 to 2.7.3.129 -would that work if not or is there a better way.  Thats the way I am doing it on my cisco that I am replacing

Hello,

Would you be able to drwa up a simple diagram of how things are configured. I think I undertstand but dont want to assume. Are the subnets that the PAN's protect the same, i.e. 10.1.1.1/24?

 

Please advise,

Worked it out with support.

 

seems like the only way to get a proxy arp response is with a NAT pool defined on the PA.
