Having two IPs from the same subnet on different interfaces or subinterfaces

L1 Bithead

what will happen if i give ip for my interface eth1 and eth1.34 from the same network . will that cause any issue ??what will happen if configure a sub interface without vlan?? Can i really configure the ip like this  if the interfaces belongs to different zone and they dont overlap the security rules??

You can't have overlapping addresses on interfaces in the same virtual router.

What are you trying to solve by doing this?

yes i agree 

then will palo alto listen to the all available ip on /28 i mean if thats the range of my external zone.?????

my eth1ip -10.20.10.10/28 which is mapped to a public ip 10.0.0.2 that is currently using for our site to site vpn connection.

i have one more public ip 10.0.0.3 that is mapped to 10.20.10.11/28 i want to dnat that ip to my web server which is located in my DMZ zone. so now i think by proxy arp it may be possible i need to test it first by creating a nat rule for the specific ip..
