Hello Guys,
I am trying to setup a proxy arp here with this asl. This is what I am doing right now. I am no great artist so I am not going to even try and do ascii art here.
This is my plan. I have an asl box with 3 nics. One is for the external , the second one is for my internal network and the third one is for my DMZ.
What I have been trying to do is to give nic #1 and #3 (external and DMZ) the same IP address x.x.x.147 so that I can simply stick my public IP's on any box in DMZ and let them be visible to the net. I only have one set of public IP's and cannot get a "transfer network".And I cannot change the ip address of my internal setup.Plus I cannot afford to "dnat" my servers in the DMZ.When I try to add another IP of the same subnet as my external NIC(this is the subnet that is in the DMZ) Webmin does not allow me to do so.I have looked at your filesystem but cannot find where I can manually make my nic and route changes. Please point me to the name of these files that contain these info and their location. I tried to use "find" but came up with nothing since I was only guessing the name of the files.
I know that with the 2.4kernel it is possible since I got it to work one time with a 2.4 kernel( by simply setting both nics to the same address and fiddling with my route tables using "ip route"and turning on proxy_arp" .What I did with "ip route" was to remove the default routes . Here is waht I did: (1)set the external nic to route to the cisco router(Uplink_ISP) and (2) setting the DMZ nic as the route for the entire subnet. I would like to know if and how I get to make such a solution work with asl.
Thanks a lot BJ
