EFW Support

hi all
on my LAN, red network has the address on subnet  192.168.1.x while the green network PCs are connected through the subnet 192.168.0.x.
A web server has address 192.168.1.2 (it is on the red network) and I want to get it from the PCs on the green network, but endian blocks traffic.
In particular, if I try to access to the server with its IP address from the green I can have access, while if I use the host name Endian says "access denied to the  chache manager".
Can you give me some advice?
Thanks in advance.

Did you try white listing it or putting a rule in the firewall to allow outgoing traffic to that ip address on the appropiate port?

Dda Thanks for your answer!
Yes of course I have already tried the solutions that you show me; I do not understand why if I type the IP address in the browser can not reach the host and if I enter the symbolic address that does not happen (note that from the outside, from the Internet, all works regularly)
Thank you again.

Are you able to ping that address?
What is your subnet mask?

Yes.
I am able to ping either  ip address and simbolic address.

All PC inside the LAN have subnet mask 255.255.255.0

Note that there is a mistake in the previous post: if I type the IP address in the browser I can reach the host and if I enter the symbolic address than I cannot reach the host (note that from the outside, from the Internet, all works regularly)

So you can ping the ip address or the url name and use the ip address in the browser but you cannot type the url name into the browser correct?
You should have put that machine in the orange zone rather than the red zone.

OK. Thank you dda.
I'll try to follow your advices.

I ran across this issue as well and for me it was the Proxy. I turned it off and I could access the site.

Hope this helps.

My real problem is that I have two web servers (two separate and independent physical machines ) that I would like to reach from the inside (from the LAN) and from outside (from internet). Setting the DNS server inside the LAN I can directly call to the two servers without problems, but for calls outside what should I do? If I set the DNS server so that calls from the Internet reach the same IP address, how  will I distinguish calls to one server from another? Instead if the calls from the Internet are directed to different IP addresses (my router can work with this configuration) how can I reach the two computer through EFW?
I hope I explained ....
Thanks for the reply.

Ok in a situation when you have two physical web servers that you want to be able to access from the internet you are going to need to use a reverse proxy. Currently I am using apache that is installed on an ubuntu server to complete this task on my network.
Once you have the reverse proxy setup you point all your port 80 traffic to the reverse proxy then it will direct the request to the appropriate server.

Have a look at this link for an overview. ubuntuguide.org/wiki/Apache2_reverse_proxies

hope this helps!

Gpalmia ...first try to run nslookup command on your endian console and see if your are able to resolve the internal address?? Otherwise you have to define your same dns which you are using on your other hosts into your endian firewall.

I have to define my dns when i had this issue ...

Secondly if you are using proxy it will use the dns which are defined in /etc/resolv.conf ....

As far as i remeber ...if you want me to confirm it for you ..i will check my firewall and tell u which dns it is using and when ..
