Public IP address needed in override hostname?

Frederiek Pascal

Hello Sophos community,

I bought a Sophos XG 106 for home use and to learn more about internet security. 

But now, I have a question about the VPN access from : https://community.sophos.com/kb/en-us/122769

I followed all steps but I was wondering what I have to type in the "override hostname" field?

Do i need to add here my public IP from my internet isp?

Cause when i try to connect with the vpn client I see this in the logs : 

Wed Dec 18 12:07:12 2019 Attempting to establish TCP connection with [AF_INET]84.197.138.2:8443 [nonblock]

Wed Dec 18 12:07:57 2019 MANAGEMENT: >STATE:1576667277,TCP_CONNECT,,,,,,

So I can't seem to connect to my firewall through vpn, but i have no clue what's wrong with my current config.

Thanks a lot

regards

Frederiek

    Hi  

    Yes you need to put the public IP of ISP in the override hostname. The NAT device ( ISP router or modem) has to be configured to forward the SSL VPN connection to the XG Firewall.

    Override Hostname : This sets the SSL VPN client configuration file to use this public IP when establishing the connection.

    Please re download the config file after setting up public IP of ISP and check the SSL VPN status, this will fix the issue.

    Hello,

    Thanks for your reply.

    I changed the hostname override to my public ip 

    I re-downloaded the config file and when i try to connect, I still get this error :

    Hi  

    I checked port 8443 status on https://ping.eu/port-chk/ and it is showing me closed.

    Please confirm if you are also getting  the same status or result if yes then you need to check on that part.

    PFA.

    sorry for my noob question, but where do i open this port? i thought this was done by following the " How to configure SSL VPN remote access" article.

    https://community.sophos.com/kb/en-us/122769 Here it's explained to add a firewall rule too, which i did, but i guess that's not for opening the port? :-)

    I mean this firewall rule like described on the KB

    Hi Frederiek Pascal,

    You have to forward port 8443 from your ISP device to firewall's WAN interface IP address. By default port 8443 is open on firewall if you have SSL VPN remote VPN configured. 

    In your case the firewall is behind ISP modem and has no direct access to the internet so you have to follow that extra step. 

    Thanks,

    thanks for your answer!

    which extra step do you mean?

    My configuration is an ISP modem (where the router function is disabled), than my sophos and than my access points for wifi.
