Hi all,
Here is what i have done so far.
i worked only on the nat.ex.com
internet
|
|
________rl0(193.23143.33)________
| |
| nat.example.com |
| |
|_______rl1(192.168.0.254)________|
|
_____|______
|___________| switch
| |
-------------------------------| |----------------------|
LAN _xl0(193.231.43.26)
| |
| app.example.com |
| ________________|
OK,
So I created on nat.example.com on rl1 a virtual interface
ifconfig rl1 alias 193.231.43.25 255.255.255.248
After that i created a route for this new interface
route add 193.231.43.25 193.231.43.33 -iface
So now i can ping rl1 rl0 & internet from the app.example.com but i cannot access this machine from the internet.
Any thoughts on that ??

In the LAN i have the other machine application.example.comI have some Public IP`s from my ISP : 193.231.43.25-30 255.255.255.248 I want to assign to application.example.com 193.231.43.27 and to route this ip trough nat.example.com Any ideea how can i do that ?
I'm having problems with your setup. Is Application.example.com at 193.531.43.27 or is it on the lan with an internal address?
If it's internal, then machines on the lan can see the internal IP, so there's no reason for it to have a public address. If machines outside the lan need to get to app.ex.com, then use natd_flags in rc.conf and point the ports you need opened on app to the local addy of app, and use the NAT's external addy for the external users of app. That would be the easiest way if you don't want to give an external addy to app.
Of course the easiest way is to just give app an external addy and plug it into the ISP supplied router. Unless app is a M$ box, of course.
See 'redirect_address' in natd(8).I believe you'll also need to assign your public IPs to the externalinterface of your NAT box.I have a similar setup, but I need to review just what I've doneto make that work...
Please help. Regards, Mihai
