Sophos XG SSL VPN, restrict access to target host by port

Malte Engelhardt over 4 years ago

Hello everybody

I have SSL VPN configured according to this manual ( Sophos Firewall: Configure SSL VPN remote access and Update the default CA (sophos.com) ). Further, I have configured firewall rules:

#1 allow VPN / External VPN users -> using Port 54322 -> To Hosts for external users

#2 disallow VPN / External VPN users -> using any port -> to any target

... other rules ...

However, I can still access any port on the target host! Is there any way to filter this kind of traffic?

Regards,

Malte Engelhardt

Hi Malte Engelhardt,

Thank you for reaching out to the Community!

Would it possible for you to share screenshots of firewall rules? I'd also suggest you run a packet capture on they firewall to ensure SSL VPN traffic is allowed with the correct firewall rule.

Monitor traffic using Packet Capture Utility in the Sophos XG Firewall GUI

Thanks,

Hi H_Patel,

unfortunately, there is nothing logged in the firewall log regarding the destination IP. I've added some screenshots.

Hi Malte Engelhardt,

Thank you for providing screenshots. I'd request you to share the support access id from your firewall with me by sending a private message.

I'll double-check the allowed service definitions and update you with the next step.

Thanks,
