Re: Unknown authentication algorithm for user.

Hi,
Trying around with 802.1x, too. User-Manager does not seem to support any needed TLS method.

Hi, You need a Queue Tree for that. Create a Main Tree, Prio 1. Then Create Child Queues for each Traffic Class you want. For the Main Queue select an PCQ type, select small queues for the childs. Traffic Classification is done by Packet-Marks. PreRouting-Chain is used for the WAN-Upload, PostRoutin...

Hi, What about mangle rules? Drop packets with source Mac 00:00:00:00:00:00, that's easy ;-) DHCP Requests are sent as UDP Broadcast to 255.255.255.255, as i remember. Please double-check it before apply it. Also, you could rate-limit DHCP-Requests with an input-rule. Also, you should review the lea...

Re: SPF fro 60Km

Have a look at some fiber shops. Which country are you asking for? The Limit is, at very first, the SPF Module. Secondly, at such long distances, the cable quality is important. Take good quality (!!!) Single-Mode Duplex Cable, select the the ones for long wavelength (~1300nm as i remember). Most of...

Re: IPSec Point to Multipoint

HI lbenzo,

Please review the basics of your IKE Policies. Have you whitelisted them to pass? I'm pretty sure you haven't.
What about switching to a Layer-2 VPN Solution using OpenVPN - i don't know your skill grade regarding IPSec, while OpenVPN is mostly failsafe.

Best regards,
