I have a working SNAT, but the src nat address is only defined in the SNAT rule. should I also add it to a lo

OKay

A/P cluster

Internet IF - 1.2.3.4/24

Internal IF - 192.168.1.1/24

S NAT rule src Internal going to internet SNAT to 1.2.3.13/32

Now I don't have 1.2.3.13/32 allocated to any interface. But the PA's know to do proxy arp for it.

As best practise should I allocate the IP as a secondary ip to Internet IF or to a loopback or just leave it un allocated.

The only issue with unallocated is I can't ping it!

Will there be a problem is I allocated it to a Lo

Hello,

Hopefully I am on the right track here, please correct me if I am not. The IP's from your ISP are 1.2.3.4/24 and as long as they are routing them to your PAN, you shouldnt need an external IP. With respect to the not responding to pings, thats not all bad since you become more 'invisible' from the internet. I actually preferr it this way but there are reasons to be discoverable.

Hope that helps.
