Port forwarding from green to red

[Guest]

[Child of Wonder]

My Endian firewall has two NICs, one red and one green.  I have a single server on the green network that has HTTP, IMAP, and SMTP forwarded to it.

Works great when someone from the internet connects to those services, however anything on my green network cannot access the services.

I am able to resolve the name to the red IP and can ping the red IP.  However if I telnet to port 25 on the red IP, connection times out.

Please help!

Thanks

No one has any ideas?  I'd have to imagine this has happened to someone else.

I also encountered similar problems, I think Endian Firewall only allows port forwarding to the DMZ - ORANGE.

You want to receive the server form green with the external ip? This does not work because your switch in green tries to find the shortest way and the packets will not use the way over the internet and you have packet loss.

You have to use the internal ip/hostname to access it from green or you put the server in blue or orange.

... it's simple...
Go to your endian web interface

Choose "network" -> modify host (or add host) I've got it in Italian!

IP ADDRESS: you server ip address, the internal one

hostname: your public domain name
domain: your public domain extension

.... for example...

My public domain, which resolves my public ip address is: mattia.com

IP: 192.168.0.1
hostname: mattia
domain: com

Click apply!
That's it!

All clients in your network will now know that the server address has to be resolved internally.

Bye, Mattia

Hi! I tried your instruction but its not working, I wonder do I have to use EFW as my DNS? My current setup is Server 2008 w/Exchange 2007 and it has to run its own DNS to work.

Thanks!
