Hi,

The situation:
- installation type: distributed
- management serwer: Dell 650,Windows 2003 R55 HFA03
- enforcement point: Dell 2650,SPLAT R55 HFA03

I want to create manual NAT hide rule and I don't have control of
upstream
router (so I can't add static routes on the router).

External interface eth0 of enforcement point: 192.168.2.1/24
Internal interface eth1 of enforcement point: 192.168.1.245/24

I want to create manual NAT hide rule for the subnet behind the eth1.
I create host object 192.168.2.100, manual hide rule (also of course
the rule permitting traffic from 192.168.1.0/24 to any destination/any
service), disable automatic ARP in global properties (I also checked
when this option is enabled) and install policy.

192.168.1.0 192.168.1.0 any original         original original
192.168.1.0 any         any 192.168.2.100(h) original original

I also follow the KB article and add to the "/etc/sysctl.conf"
net.ipv4.conf.all.proxy_arp = 1
net.ipv4.conf.default.proxy_arp = 1

+
arp -s 192.168.2.100 <FireWall_external_MAC_addr - eth0> pub

and reboot the gw.

The problem is the above configuration doesn't work. On the upstream
router "show arp" command shows:

Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  192.168.2.100           0   Incomplete      ARPA

The enforcement point doesn't want to proxy arp for the 192.168.2.100
with its own MAC of eth0.

Any clues? Can anybode help me?


Kind regards,
Maciek
