internal Network can't reach Public IP

Elvis Altherr

Hi all

I recently bought a Sophos SG115w Firewall and everything works fine expect the following:

I have a internal Network 192.168.1.0/24 with fixed ip Addresses and now i have to problem that i can't access the Public IP 62.2.208.170 from within the internal network even i added a Rule to allow this (see Attachments)

If a do a telnet to the Public Address or a Web Access a Timeout Occurs

Same with the Webaccess

What I'm doing wrong?

In the Log the Access seems ok but it doesn't work

    Ok so edit rule 19, make the source your internal network, the services any or whatever specific ports you want i.e. ports 80 & 443 for web browsing, them make the destination your wan.

     

    You can do this by clicking on rule 19 edit, deleting the three you have set for source, services & destination.  Then click on the folder in the source part, and go to the search bard on the left, type LAN to find your internal LAN, you can drag and drop it into the source part.  Do the same for services with Any and the same for destination with WAN.

    Also in order for us to see NAT you need to take another screen shot, it is under Network Protection --> NAT

     

    It is right under the firewall menu option.

    Hallo Elvis and welcome to the UTM Community!

    I'm confused as to why you're trying to reach an IP on the External interface.  Maybe you need Accessing Internal or DMZ Webserver from Internal Network.

    This feels like a routing problem, but let's confirm that by doing #1 in Rulz - was there anything in the Firewall log?

    You will also want to read #3, #4 and #5 in Rulz.

    Cheers - Bob

    Hi Bob

    Thanks for your reply. I will check the suggestions. Yes in the Log the Access is shown as allow. I also think this coud be a routing problem,coze if i try to access the external address from within the UTM it works (telnet from the shell direct on the FW)

    Hi Bob and all

    Thanks for Tipps the Article with the Internal DNS Server helped me. Will say i put a separate DNS Server for the Domains / Server (192.168.1.43) within the C-Class Network 192.168.1.0/24 and it works, means i can reach now the Servers behind the FW
