NAT with Proxy ARP
Hello Gurus!
I'm currently trying to configure NAT using proxy ARP on a SunOS 5.8 .
This box is running Check Point FW1 that sits behind my internet router.
I have a server that is connected to the firewall box. I want to translate this server using proxy ARP.
Settings:
==========================================================
A) FW box "Public" interface IP address: 10.1.1.1 (in actual situation uses real public IP).
B) FW box internal interface IP address: 172.16.1.1
c) Server interface IP address: 172.16.1.5
I want the server to be translated to the IP 10.1.1.5.
I have gone through these steps in order to set it up
Steps:
=========================================================
1) Set the FW interface to answer for ARP request for 10.1.1.5
arp -s 10.1.1.5 08:00:20:c4:4a:e6 pub
08:00:20:c4:4a:e6 is the FW ethernet address.
2) Add routing entries to send traffic to the right destination
route add -host 10.1.1.5 172.16.1.5
==========================================================
There are currently 2 other servers NATted this way on the firewall and they work just fine.
Firewall rules allow certain tcp connections and icmp to to 10.1.1.5 and 172.16.1.5
Am I missing anything? What should I do to make it work...
Been trying for the past 4 hours and its already past midnight
Thank you so much for any help!
