My ISP has DHCP-assigned IP-addresses. I wonder if someone has tried using proxyarp for a DMZ with DHCP-assigned public IP?

proxyarp and masq ip
Would it be considered normal that a system behind a shorewall box that was setup for proxyarp and able to be reached from the trusted side of the net just fine on the proxyapr ip address would if it were to talk out to the world show as traffic not from the proxyarp address but the firewall''s own address or the masquerading ip used by other zones? We had not really noticed this as an

odd problem with proxyarp and DNAT
I have some hosts in a DMZ zone with proxyarp. In my local zone I have a host to which I DNAT. I have discovered that I can reach the host in the local zone by attempting to connect to the fw (As expected) or ANY proxyarped host in my dmz zone (as not expected). Is this normal ? (I''ve just discovered that actually the dnated host answers to requests sent to any IP routed to my host!)

Samba and ProxyArp
Hi As per my follow up mail I implemented the ProxyArp configuration as per the Documentation on the Web site and all seemed to be working correctly. However, the one thing that doesn''t seem to be working properly is Samba. I have Samba running on the FW machine and one of the servers 192.168.0.8 on the Local Lan.

config question for proxyarp hosts?
I''ve got a serious mess of NAT on our firewall/router systems at the corporate office which seems to do nothing other than confuse the heck out of people. What I''d like to do is gradually migrate the hosts on the various DMZ networks away from private IP addresses and NAT over to public IP addresses and proxyarp. What I''m wondering, before I start this, is how do I

Proxyarp vs DNAT
Hello list, I am in the process of switching from IPCOP to Shorewall s the firewall for our small office. I very much like the fact that Shorewall runs on top of the same OS (openSuSE 11.4) that I run on the server and my desktop. Our setup is fairly straightforward. We have 8 static ip addresses from our ISP, which provides a cable modem and a Cisco 800 series router. The ip addresses are

ProxyARP in a Routed environment
Hi, In a routed network setup , is it possible to use ProxyARP given the condition that the shorewall external interface and the DMZ interface are in a completely different network . That means the gateway of the External interface and the hosts in ProxyARPed DMZ zones are in different network. eth0 ---in 220.227.X.Y/30 -- shorewall external interface eth1 ---in 220.227.A.B/27 -- shorewall
