I have a Linux box I use for a firewall with iptables, and I need to put my mail server on the right ip address for proper reverse DNS Lookup.
So I can take inbound packets and NAT them to the mail server, but I need to take outbound packets from the mail server, and send them on a different IP address. The IPTables sends everything out on the same IP, which is 1, but I need 5.
I thinking maybe I could add another gateway, using route, below is my main route, I'd like to add 192.168.3.5 to use a gateway of 18.104.22.168,
Am I on the right track here?, I could use some help on this
/sbin/route add default gw 22.214.171.124 dev eth0
/sbin/route add -net 192.168.3.0 netmask 255.255.255.0 gw 192.168.3.1 dev eth1
I had 2 addresses bound to the mail server adapter, and was only SNAT 1 of them, so I added a SNAT to the other address, and now the mail server responds on the correct ip address for reverse dns and resolves correctly.
So I didn't need a 2nd gateway address, or need to add any additional routing, turned out to be pretty easy. Only took me years to figure out.
I want to take all new smtp packets generated inside the network, and send them out on a different ip address, and not the gateway address, so the ipaddress reverses back to the correct ptr record, indicating it's a mail a server that belongs to my domain.
Right now, the packets go out on the gateway, with a different reverse ptr record.

I used the Microsoft Web Platform Installer to install mojoPortal into a website I created in IIS8 on Windows Server 2012, and whenever I try to go to one of the pages in the site, I get a 404 Not Found error. IIS has done this for several testing sites I have created, and it is getting annoying. Any suggestions on what could be going awry?
EDIT: I was able to get an error stating something about wildcard script maps. I will use that to look into other possibilities.
EDIT2: IIS seems to think that the .aspx file extension has no associated handler, but a handler for it exists in the list. I will look into this further. It might be a missing role/feature.
EDIT3: It turns out IIS wasn't redirecting correctly. I still need to figure out what went wrong there.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
I WANT TO BUILD A WORKING,SECURE,RELIABLE,AND EFFICIENT WIRELESS SYSTEMS FOR SENSOR NETWORKS AND I WOULD LIKE TO KNOW THE HARDWARE AND SOFTWARE COMPONENTS THAT IM GONA USE TO DO IT.PLEASE HELP ME I AM WAITING FOR ANY GOOD REPLY THAT WILL HELP ME
Need more info... what kind of sensors? how do you intend to communicate with your sensors? how secure does your network have to be (commercially secure or military grade)? does your network have to be something already commercially available? does your network have to have a certain topology?
i want the cheapest sensors that are available on the market,i want them to communicate in a centralized way and i also want my network to be commercially secure and even if something that is similar to a wireless network that is already available but not exactly the same i would love to have a ring or star topology for my network. i am waiting for your reply as i am in need of help, thank you for your time
Apart of that... Which kind of sensors are you interested in? and what do this question has to do with the "Hosting and servers" topic?
Give us more descriptions, "the cheapest in the market" is not good enough...
i.e. I can use an inductive sensor to detect metal proximity, I can use a ultra-sound sensor to detect physical bodies, I can use a laser sensor to detect distances, I can use an optical sensor to detect pgysical bodies, I can use RFID chips, and even artificial vision... All of them have different prices but event the most expensive one can be the cheapest one if the application requires it...
Summarizing, read the posting guidelines, follow them, give us as much information as possible and then probably someone will be able to help you.
