SSL-VPN

Hello Nazir,

Thank you for contacting the Sophos Community.

The logs don't show the SSL VPN trying to connect to any Public IP, but rather Private IPs, (unless you tried to obscure the Public IPs), does your XG has a Public IP?

If not, you’ll need to find the Public IP of the upstream device, and add that to the SSL VPN Override hostname (Configure >> VPN >> Show VPN Settings >> Override hostname.

Regards,

Hallo 

I am still not able to connect SSL VPN can you advice me where the problem can be ?

Hello Nazir,

can you give us a screenshot of your LANCOM configuration regarding the port-forwarding?

Hello Philipp, 

thank you from your answer, below you can see my port-forwarding in Lancom Router as well my Lancom WAN and LAN configuration 

192.168.10.2 ist my sophos-firewall wan-port.

Regards

Nazir

Hello Nazir,

that notation "8.443" seems odd to me, can you chek this?

Also, we have had some problems with Lancom configuration through the webinterface, can you try configuration with LANconfig?

Hello Philipp, 

I didn't understand what do you mean that notation 8443 seems odd to you? could you please a little bit explain it what should I do here ? I do always the configuration with LAN config tool.

Regards

Nazir

Hello Nazir,

Most likely it's no longer necessary but just in case this was not clear yet; with "notation" jprusch's literally meant the "." in between the 8 and 443. Since it shows in your picture "8.443" in stead of "8443". I've searched for pictures of different kinds of port forwarding tables and none of the common results show port numbers with dots in between the digits.

Kind regards,

Timo

Hello Time, 

unfortunately my problem is still not solved and I am surprised in this big community there is no one to support me in order to fined the Problem I thanks from Yash and Philip they tried to solve my problem but then I have got no more advice from them.
in case of "." which you have meintioned I want tell you that the LANCOM Router put "." automatically

It is quite simple. If you do a packet capture on the firewall (Diagnostic) and do a BFP String of "port 8443" and the result is no packets on the firewall, it means the other components does not forward the requests to the firewall (and the issue is not on the firewall itself). 

Hello Toni, 

I have did what you recommend and got below, do you have any recommendation for me?

as you see the port is open to out side as well.

I did not unterstand this why ?

Just to ask a basic question, where in your diagram are you trying to connect to the VPN? (Outside, from the internet, or inside?) You need separate permissions to connect from WAN versus LAN (or WIFI or any other zone), if that matters.

I am connecting from outside through WLAN see below diagram.

You need to set the switch above to enable/on. 
If you press refresh and do not see any traffic, then the device infront of the firewall accepts the traffic and does not forward it. 

sorry I did not understand what you mean (set the switch above to enable/on.)

If you mean this when the switch on and I do refresh I get below see the 2 screenshot. but if I switch off the BPF and set port 8443 then the switch get no more on and when I refresh there is no more traffic available see the 1 screenshot

You need to do " port 8443 " 
But likely its not getting passed by your Router.
