Web server behind two firewalls
Hi all.
This is sort of a windows/linux question, and I wasn't sure whether to post in Servers or Networking either.
I am trying to set up a Windows Server 2008 R2 web server behind two Ubuntu Server 10.04 firewalls/routers.
The idea of having two of them, is for redundancy. Right now load balancing is not under consideration.
Lets say for example, the IP are like this:
Firewall1, internal interface 10.0.0.11
Firewall2, internal interface 10.0.0.12
Web server, LAN IP 10.0.0.22, gateway 10.0.0.11, in advanced options second gateway 10.0.0.12
To cut a long story short, it all works as planned, only it seems the server is listening on only one gateway at a time. Is this some kind of general networking limitation, or windows networking limitation?
Would it help if one subnet is 10.0.0.x and the other 10.0.1.x for example?
Both firewalls are online but for example with Remote Desktop or FTP you can only get in from one at a time.
Is there anything that can be done for both to be "active" at the same time, or this kind of setup is impossible and I should just drop one machine and have a single gateway?
Thanks a lot for any ideas. I have been googling around but haven't found anything specific to my case.
Darko.
