[strongSwan] loopback ip address range

[Naveen Neelakanta]

Hi,

I would like to know how can i make use of loopback address inside
Linux NameSpace.
I have two veth pair lan0-lan1 and net0-net1 , lan1 and net1 are
attached to  namespace.
net0 and lan0 are attached to root namespace.

Root Name Space
lan0-> 127.10.0.1
net0-> 127.11.0.1

Name Space TEST
lan1 -> 127.10.0.2
net1 -> 127.11.0.2

I want to send traffic to lan0 ->lan1->net1->net0 , the issue i am
facing is that i see ARP
18:19:41.542724 ARP, Request who-has 127.10.0.1 tell 0.0.0.0, length
28 in net0 interface .
I have the forwarding enabled, how can i get rid of the arp issue.

Thanks,
Naveen
