Bridge problems

Post by jnbruguer » Mon Nov 09, 2020 8:18 pm

Good afternoon everyone, I am quite new to this although I have installed some vpn with this software with a fantastic use.

Today I installed the software on a new Dell server and I am encountering the following problem:

Sometimes the Localbridge sends the DHCP ip address and sometimes not, I attach a log. As you will see, in some connection it connects the user but does not give him IP

I can't understand what happens?

Please can you help me?

Thanks in advance

Joan

Hi people,
I'm working hard to try understand what happens with local bridge.

It works fine with 2 sessions but the local bridge don't give an IP to the 3rd session an more.

I read the documentation and I think that the problem is the ethernet controler, this is:

Broadcom NetXtreme E-Series Advanced Dual-port 10GBASE-T Ethernet LOM

It's a new Dell server, and I read in documentation that recomended adapters are:

Intel Intel PRO or Gigabit Adapter series
100Base-TX
1000Base-T
1000Base-SX
1000Base-LX
10GBase-SR
10GBase-LR

Broadcom Broadcom NetXtreme series
100Base-TX
1000Base-T

3Com 3Com series
100Base-TX
1000Base-T

Do you thing that the Broadcom new adapter it's the problem?

Thanks
Joan

Hi Jnbruguer,

Are you running Windows on the Dell as a physical server? Or the Dell is virtualized, and the SEVPN is running as a VM?

If you are running the Dell as a physical host, check the switch to ensure you are not implicitly disabling promiscuous mode and mac spoofing (port security). Both options are required for bridging to operate.
